1. PREFACE

An overview of the results and metallurgical analyses of the

findings of impact tests conducted at the National Bureau of Standards

on samples of tank-car materials submitted by the Federal Railroad

Administration is presented. The submitted samples were taken from

tank cars which had been involved in service accidents during the

period January 1970 to January 1971. One of these tank cars had been

fabricated from ASTM A212 steel and the remaining four tank cars from

AAR TCI 28 steels. The impact test data were reported earlier in four

tank-car accident reports.

It is recognized that the analyses given here are based on only

a limited number of plates, which cannot be considered a sufficiently

large number of samples to justify a definitive comparison of the

impact properties of the various grades of steel from which the cars were constructed. However, as a data compilation detailing the

characteristics of tank car steels, this report can serve as a basis

for further analysis and as an example of how impact data can be

handled to derive a general understanding of the fracture characteristics

of these materials. The data do allow a comparison of longitudinal,

transverse, and short transverse properties in these plates, and they

illustrate impact toughness trends as they relate to chemical composition,

grain size and cleanliness of the specific plates studied. Further,

they illustrate the comparative results that are expected from CharpyV-notch tests vis-a-vis those from Dynamic Tear tests for the steels

tested. When these various findings on the impact properties and on

the metallurgical factors affecting them are considered along with

the observed behaviors of those materials in service and with the

service requirements which can be developed from larger numbers of

service failures, reconwendations as to approaches to improved materials

and improved specifications for such materials can be formulated.

Although some general conclusions (based upon results of the program

and of the analyses of the available data) are given here, what is

needed are specific recommendations on materials requirements for

tank-car applications and on the various approaches that can be taken

to meet these requirements economically.

Impact Properties of Steels Taken

From Four Failed Tank-Cars

2. INTRODUCTION

The Federal Railroad Administration (FRA) has sponsored research studies

aimed at the development of knowledge that could be used to prevent or minimize the sometimes "catastrophic effects of tank-car failures. As part of

these studies, the FRA has requested that the National Bureau of Standards

(NBS) conduct metallurgical analyses on steel samples taken from failed tank cars involved in four accidents. The results of the NBS analyses are given in

four reports n -4) , and in a summary report^ ' titled "Analysis of Findings of

Four Tank-Car Accident Reports". With minor exceptions, the summary report

analyzes all findings of the other four reports except for the results of

impact tests. The impact test results are analyzed in the present report on the "Impact Properties of Steels Taken from Four Tank-Car Accidents" ^ and so this report is complementary to the sumnary report.

This report deals with impact-test results of samples of six steel

plates and three weldments taken from four failed tank cars, each from a different tank-car accident site. The six plate steels include four produced

to specifications of AAR-TC128 and two produced to specifications of ASTM

A212-B; three of these plates represent head plates and three represent

shell plates. The weldments represent shell-to-shell and head-to-shell

weldments of TC128-B steel plates.

Although the samples were taken from tank cars that had failed in

service, it is believed that the samples were judicously selected so that the

impact properties reported in the four reports that are here summarized and

reanalyzed are germane to the plates in the tank cars in service, except

where noted otherwise.

3. IMPACT TESTS AND PROCEDURES

Two types of inpact tests were used in this investigation: standard

Charpy V-notch (CVN) tests and dynamic-tear tests, (DT). A sunmary of these

tests and the samples from which specimens were taken is given in Table 1.

Test methods used for the DT tests were those developed [6,7] by the Naval

Research Laboratory and the test methods for the CVN tests were in accordance

with ASTM Designation E 23-66.

The CVN tests were conducted on specimens from three head-plate samples

and three shell-plate samples taken from four accident sites. These six

plates represent three grades of steels: One head plate and one shell plate

of ASTM A212-B steel, two shell plates and one head plate of AAR TC128-B

steel, and one head plate of TC128-A steel. Additional specimens represent a weldment of TC128-B steel plates taken from the Callao accident: These

include weld-metal specimens and weld heat-affected-zone (HAZ) specimens of one head plate and one shell plate of AAR TC128-B steel.

The DT tests were conducted on specimens from one head and one shell

plate of TC128-B steel taken from the Callao accident.

For all sets of impact specimens, tests were conducted over a temperature range selected to show the transition from ductile to brittle

fracture. In addition, the DT test specimens* were tested at elevated

temperatures up to 1300 F. This was done to simulate the response of the

steel to fracture under the broad range of temperatures likely to be

encountered when a tank car is engulfed in a fire.

The Charpy specimens were standard size of .394 x .394 x 2.165 inches

and they were machined from the quarterthickness location of the plate steel or weld-metal, except for those from the HAZ of the Callao head- and

shell-plate samples, from which the specimens were taken from the midthickness

location.

Specimens for the DT tests were full-plate-thickness specimens

(nominally 11/16-inches thick for the head-plate specimens, and 5/8-inches

thick for the shell -plate specimens), with length and width dimensions of 7 1/8 and 1 5/8 inches, respectively, and with a saw-cut and cold-pressed notch

with a depth of 3/8 inch.

These specimens were at temperature for about 25 minutes prior to testing.
3.1 Orientations of Specimens

The orientations of specimens and the notch configurations used in

impact tests and the orientation codes for these various types of

impact- test specimens are given in Figure 1. Each type of specimen had

a 2-letter code. The first letter of the orientation code represents the long

axis of the test specimen and the second letter represents the direction of

crack propagation; the letters L, T, and S were used in these codes to

represent three orthogonal plate directions: longitudinal, transverse, and

short- transverse (or thickness) direction. The longitudinal direction is the

principal (or final) rolling direction and the standard longitudinal and

transverse configurations were therefore respectively designated LT and TL.

Thus, the LT specimen has its long axis in the final rolling direction of the

plate and the notch is oriented so as to produce crack propagation in the

transverse direction (perpendicular to the rolling direction) of the plate.

The LT and TL specimens are the standard longitudinal and transverse

orientations, and they were used for CVN tests of all head-plate, shell-plate,

and weld-metal steels* tested, as well as for the DT tests of head-plate and

shell-plate steels. Specimens of these orientations relate to the cases involving through-thickness cracks that grow in directions parallel to the

plate surfaces, and the results of these tests are generally considered to be

most important.

The LS and TS specimens are, respectively, longitudinal and transverse

specimens that are notched to give crack propagation in the short- transverse

(or thickness) direction of the plate. CVN specimens tested with these

orientations include the Belle B-head plate of TC128-A steel and two TC128-B

steels, Callao A-head and shell No. 1. Specimens with these orientations

relate to cases involving cracks that propagate in a direction perpendicular

to the plate surfaces, such as in the initial rupture of a plate in a tank car

that is impacted by some external force.

In addition, TL specimens of the weld heat-affected-zone (HAZ) regions of

the head-plate and shell-plate TC128-B steels from Callao were tested. It

is noted in report No. 4 (ref. 4) that the HAZ head-plate specimens are not

of the true TL orientation as defined here; they are roughly intermediate

between TL and LT as is obvious in Figure 5 of that report (see "Impacts

HF" vis-a-vis "Rolling Direction").

3
The SL and ST specimens are short-transverse specimens with notches that

give crack propagation in the longitudinal and transverse plate directions,

respectively. CVN specimens with these orientations were tested only for the

"A" head-plate of TC128-B steel from the Callao accident. These orientations

may relate in a general sense to cases involving fracture along planes

parallel with the plate surfaces, such as occurred along the fracture edge of

Callao plate K-7--in reference 4, this is the edge of the area marked #7 in

Figure 9 and area N in Figure 26. This type of fracture is commonly called . lamnellar-tearing.

3. 2 Data Analyses

The experimental data for impact tests were analyzed by a computer

method that calculates the curves of best fit for the available data using

least-squares analyses and then plots the calculated curves and the

experimental data using an incremental digital plotter.

These computations were made for a total of 20 different CVN data sets,

each of which represents only one specimen orientation for one of the six

steels tested. For these CVN tests, a complete data set includes results for

three fracture criteria: percent-shear-fracture appearance, energy

absorption, and lateral expansion. Computations were also made for four DT

data sets representing two of the six steels. For the DT tests, a complete

data set includes results for only the first two of the three criteria, as lateral expansion is not measured in the DT tests.

The results of the computer analyses of all except four of the CVN data

sets were presented earl ierv2-4) . jhe four exceptions are analyses of the

Belle data. Thus, the results of the computer analyses of these four sets,

each having data for three fracture criteria, are presented here in Appendix A

Tables 1 through 4 and Appendix A Figures A, B, and C: Included are a complete

data set for each of four specimen orientations tested: LT, TL, LS, and TS.

Each of the Figures shows all data and results for one of the fracture

criteria. The scales used on the axes for these plots are those established

in earlier reports^ » in which computer analyzed data were presented.

Therefore, comparisons of the various data collected to date can be readily

made by overlaying two or more plots. The raw data* for these tests of the

Belle sample had to be reanalyzed for this report because the computer

method was developed after the previous report"' had been issued.

* The raw data from lateral expansion measurement was not taken until this

computer analysis was made. Thus, it was not reported earlier^').

4
The 20 individual CVN data sets were combined in various ways to make

comparisons and analyses given in this report. Calculational methods used for

individual data sets are different from those reported here for combined data

sets. The calculational results of the combined data sets give the best-fit

curve based upon the weighted mean value for all data at each test temperature , whereas computed curves for individual data sets are based upon the

individual data points at each test temperature. This new method of

calculation using the weighted mean values is considered desirable for reasons

not germane to this discussion, but it is noted that this method was used

only when more than one data set was combined to make a new, larger set to be

analyzed by computer methods.

4. RESULTS AND DISCUSSIONS OF CVN AND DT IMPACT TESTS

The results of CVN tests of the 20 individual data sets and of 18 data

sets that include combined data from various of these individual data sets are given in Figures 2 through ]4xcind in Appendices A through F.* The results of

DT tests were given earlier^^^. For individual data sets, the figures show

only the calculated curves that represent these data sets. For combined data

sets, the figures show both the raw data and the calculated curves; in

addition, the appendix tables give this same inforrration- for the combined data

sets. Appendices of previous reports'^"^) gave this information for the

individual data sets*.

A summary of the findings of CVN test results for the six plate steels, one weldment, and two heat-affected zones is given as Table 2. In general,

trends observed in the energy absorption (E. A.) data are similar to trends

observed in the lateral expansion (L. E.) data, and the observations of CVN

test results are generally similar to those of the DT test results. Thus, for

brevity, the discussion to follow frequently will refer only to E. A. data of

CVN tests, with the understanding that similar behavior obtains for either L. E. data of CVN tests, or E. A. data of DT tests (which are discussed near the end

of this report).

One exception to this is the presentation of the individual sets of

the Belle data. The plots of these data and calculations are given in

Appendix A.

5
Various comparisons of CVN test results are made in this report. These

include CVN studies of: (1) effects of orientation of specimen and notch--six

orientations were tested for one steel and four orientations were tested for

each of two additional steels; (2) the relationship between the longitudinal

(LT orientation) and transverse (TL orientation) test results for the combined

data for all six steels tested, for the combined data of only the three

head-plate steels tested, and for the combined data for only the three

shell-plate steels tested; (3) a comparison, on a plate-by-plate basis, of

the six steel plates; (4) a comparison of the combined data from the three

head-plate steels with that from the three shell-plate steels, (5) a comparison of all data from the four MR TCI 28 steels with that from the two

ASTM A212-B steels; and (6) a comparison based on the three grades (according

to the ASTM or AAR specifications) to which the steels were produced. Almost

all of these are new calculational results that are tabulated in the

appendices. These include calculations for all results shown in Figures 4

through 6 and in 9 through 12 and for four of the eight sets of calculations

made for Figures 13 and 14. Summaries of these various calculational results

are given in various summary tables numbered 2 to 14 for individual and/or

combined data sets.

Each of the Figures represents a given type of comparison used in the

analyses and discussions of this report. Within each figure number, there are three lettered frames, one for each of the three fracture criteria:

Percent-shear-fracture appearance is the A frame, energy absorption is the B frame, and lateral expansion is the C frame. The same scale is used for all B and C frames (of the B and C figures) in the body of the report. The scale

for all A frames is also held constant throughout the body of the report.

However, these scales differ from the scales given in the three figures of

Appendix A in whiehthe Belle data were plotted on the same scales used-in

previous reports ^ "

. In addition, it is noted that the scales used^ ' for

plots of E. A. data of DT tests were based on the understanding that these E. A.

values of DT tests are about 10 times the values obtained in CVN tests

(due principally to the larger areas of the fractures in the UT test

specimens). Therefore these energy values were divided by 10 so that they

could be plotted^^' on the same frame with the CVN data with which they were

to be compared.
Each Appendix gives the observed and calculated results for the figure

of the report that it represents. These results are given as a series of

tables. The sequence of presentation of the tables within an Appendix

corresponds to the sequence given in the corresponding figure. This sequence

is given in the figures under the words SPECIMEN IDENTIFICATION, shown in the

upper left-hand corner of each frame of the figure. The tables within an Appendix are thus designated lA, IB, IC; 2A, 2C; etc., with the A, B, and C

letter designations representing the three fracture criteria (as discussed

above), and with the numbers 1, 2, etc. representing the various classes of

data that are listed (binder the words SPECIMEN INDENTIFICATION) in the

corresponding figure. Some appendices contains LT data from one figure and

TL data from the very next figure; for these appendices, the number sequence

in the appendix includes the list for the LT data sets and then the list for

the TL data sets of the second figure.

4.01 Transition Zone

The transition zone begins at the highest temperature an the lower shelf

and it extends to the lowest temperature of the upper shelf. The impact test

results for individual data sets and those for the combined data sets indicate

that within a given data set, the transition zone begins and ends at roughly

the same temperatures irrespective of the fracture criteria. This is observed

(in the figures) by comparing the plotted curves of the A, B, and C frames for

a given set of data. Further, it is noted that with increasing temperatures

in the transition zone, the magnitude of the values of E. A. in DT and CVN

tests (and of L. A. in CVN tests) is roughly linearly related to (nearly

proportional to) the magnitude of the percent shear-fracture-appearance (SPA)

values.

4.02 Lower-Shelf Behavior

The lower shelf extends from very low temperatures up to the temperature

of the lower limit of the transition zone. For all orientations of specimens

tested, the percent SFA on the lower shelf is zero or nearly zero, and the

values of energy absorption vary only over a very narrow range of low values

(i.e. low in relation to upper-shelf energy values) for either CVN or DT

tests. Similarly, in CVN tests lateral expansion values in the lower-shelf

region are low in magnitude and narrow in range.

4.03 Upper-Shelf Behavior

The upper shelf begins at the upper (temperature)l imit of the transition

zone, and it extends to all higher temperatures used in the tests. Along the

upper shelf the SFA is 100 percent, for both DT and CVN tests and for all

orientations of specimens and notches. The magnitudes of the upper-shelf

values of E. A. and L. E. are governed, in part, by the directionality of the

microstructure of the material, and therefore, the effect of this

directionality on impact properties can be assessed by tests with specimens

having various orientations of axes and notches.

7
4.04 Transition Temperatures

The temperature at which a given value of one of the fracture criteria

is met is called a transition temperature (TT). Three arbitrary transition

temperatures have been chosen for the purposes of the discussions given in

this report. These are the 15 ft-lb TT, the 15 mil TT, and the 50-percent SFA

TT. In metallurgical analyses, transition temperatures can be valuable for

characterizing significant differences in the fracture properties of steels,

and they have been used (on an emperical basis) for determining the

suitability of steels for various applications, in which fracture by impact

loading and in which rapid crack propagation are important. The arbitrarily

chosen transition temperatures mentioned above are not to be taken as reconmendations of suitable criteria for tank-car steel specifications; They

were chosen arbitrarily for the purposes of the discussions of the results of

calculations based on the impact-test results of six plates taken from failed

tank cars.

4.1 Effects of Orientation of Specimen and Notch

Three of the six steels were tested in only the LT and TL orientations,

two steels were tested in four orientations (LS, LT, TS, and TL), and one

steel was tested with six orientations (LS, LT, TS, TL, ST, and SL). Figure 1 gives the orientation code. The results for four orientations of the Belle

sample are presented in Appendix A, as Figures A, B, and C and as Tables 1, 2,

3, and 4. The results for four orientations of the Callao shell-plate K-5 are presented as Figure 2, and those for six orientations of Callao head-plate K-1 are presented as Figure 3. The results for the other three steels tested with

only two orientations were presented in earlier reports^^"^^

The effects of orientation of specimen and notch are similar for each of

the steels tested. In general, the orientation of the specimen and the notch

(1) greatly affects upper-shelf values of lateral expansion (L. E.) and of

energy absorption (E. A.), (2) affects the transition temperatures at which a given level of E. A. or L. E. is obtained; and (3) has little affect on the

lower-shelf values of L. E. and E. A., or on the temperature limits of the

transition zone, or on the 50-percent- shear-fracture-appearance values.

Pertinent CVN test data (from the Belle sample and from the Callao head and

shell plates) in support of these findings are given in Table 3. In addition,

the plots of Figures 1 and 2 and of Figures A, B, and C of Appendix A are good

visual aids for understanding these behaviors, which are described below.
4.11 Upper-Shelf Behavior For Various CVN Orientations

The upper-shelf values for a given steel vary greatly with orientation

of the specimen and with orientation of the notch. As shown in Table 3, for a given steel, the values for CVN tests decrease in the order LS, LT, TS, TL,

ST, SL, with the values for the ST and SL orientations being nearly equal.

For example, for the Callao head plate steel, these values are, respectively,

85.9, 54.0, 45.2, 37.5, 15.8, and 13.9.

As a function of CVN specimen orientation, the shelf-energy values thus

decrease in the order: longitudinal specimens, transverse specimens

j

short-transverse specimens. Similar results are shown for the DT tests; their

energy values decrease in the same order: LT, TL. This general behavior is

believed to be due principally to the morphology of inclusions in the steel.

An inclusion can be thought of as an orthogonal parallelepiped, with 3

orthogonal directions L, T and S as defined earlier. With this model, the

dimensions of the inclusion in these directions are greatest in the L direction and smallest in the S direction. If the "plane" of the inclusion is

defined as that plane which contains the L and T directions (the two longer

dimensions), then the effect of inclusions on the observed results of these

impact tests is consistent with the following explanation for the energy-absorption

and lateral -expansi on data.

Fracture of short-transverse specimens (ST and SL orientations) occurs with the least amount of energy absorption because the fracture plane in these

specimens is parallel with the "plane" of the inclusions (i.e. it contains the

L and T axes of the inclusions). In addition, when the steel is bonded the

fracture plane is parallel to the alternate layers of the banded

microstructure. These geometric realities detract from the energy absorption

in short- transverse specimens. In the other orientations, the fracture plane

is perpendicular to the alternate layers of the microstructure.

In transverse specimens (TS and TL orientations), the fracture plane is

perpendicular to the "plane" of the inclusions and it contains only the

longest and shortest (L and S) axes of the inclusions; thus, in these

specimens the progress of the crack front is damped more frequently with the

tough metal matrix which contains the inclusions, and energy absorption is

accordingly increased.

9
In the longitudinal specimens (LS and LT orientations), the fracture

plane is perpendicular to the "plane" of the inclusions and the fracture plane

must cut across (or bisect) the inclusions. Thus, the fracture plane contains

only the two shorter axes (T and S) of the inclusions, with the results of a further comparative enhancement of the damping action from the tough metal

matrix and a concomitant increase in the energy-absorption value required for

fracture.

For a given specimen orientation, either longitudinal or transverse,

crack propagation in the short-transverse (S) direction requires more energy

than in the corresponding transverse (T) or longitudinal (L) direction , i.e.

LS compared with LT, and TS compared with TL. This occurs despite the fact

that the pair of inclusion axes contained in the fracture plane is the same for both orientations (for LS and LT or for TS and TL). Therefore, this

effect is believed to be principally due to microstructural banding in the

steel. In a banded carbon-manganese steel, there exist alternate layers of

tough ferrite and a comparatively brittle ferri te-pearl i te mixture. Crack

propagation in the S direction, in the LS and TS specimens, occurs by fracture

which progresses through al ternate layers of brittle and tough materials, with

the net result of an enhanced damping action from the tough material in the

alternate layers; this phenomenon would be expected to give rise to greater

energy-absorption values when compared with the values for the corresponding

fracture along the T or L directions. Crack propagation in the T and L directions occurs through all layers of the material simultaneously, and this

propagation of a crack would be expected to require comparatively less energy.

4.12 Transition-Zone Limits of Temperature for Various CVN Orientations

The results given in Figures 2 and 3 and in Appendix A indicate that,

for a given steel, the CVN transition zone begins and ends over roughly the same range of temperatures irrespective of either the fracture criteria or the

orientations of either the specimen or the notch. This is particularly

evident in the percent-shear-fracture-appearance (SFA) plots, which

graphically show this behavior. For example, in Figure 3A, the Callao

head-plate steel shows this behavior, and in Appendix A the Belle sample shows

it. For the Callao shell plate, shown in Figure 2A, an exception to the above

behavior is observed for specimens designated STB, which have the LS

orientation (longitudinal specimens with crack propagation in the

short-transverse direction). The results for these specimens were so highly

variable that the transition curves could not be defined from the available

data sufficiently to render them meaningful.

10
4.13 Effect on Notch Orientation on the CVN Transition Temperatures

As was discussed above, for a given steel the limits of the transition

occur at the approximately same temperatures irrespective of the fracture

criteria and irrespective of the orientations of the specimens or of the

notches. In addition, the values of the fracture criteria in the lower shelf

are relatively independent of the orientations. With this in mind, it becomes

apparent that for the steels tested, either the 15-ft-lb or the 15-mil

transition temperatures will tend to be in the inverse order of the

upper-shelf values of either energy absorption or lateral expansion. For

example, in Table 3, the shelf-energy absorption values for the head plate

K-1 decrease in the order LS, LT, TS, TL, ST, SL and the corresponding 15-mil

transition temperatures for these specimens are respectively 10, 41, 64, 170,

and 175 F. The transition temperatures for each of the other steels in the

table tend to follow this same trend for their various orientations of

specimens and notches, but the correlation is not as good due to the variability of test data and to the resulting variability in the curves calculated

to fit the data.

This variable behavior in the 15-ft-lb and 15-mil TT values is not

observed to occur in the case of 50-percent SFA TT values. In fact, the

50-percent SFA TT values are relatively invariant, even when the upper-shelf

E. A. and L. E. values vary widely. Table 3 shows that for a given steel,

each of the 50-percent SFA values for the various orientations tested are,

in general, within 10 F of the mean value. This invariant character of this

fracture criteria points up its fundamental character and hence its usefulness

an a guideline for determinations of real differences in behaviors of

materials.

4.2 Orientation Effects in Combined CVN Data

The combined data sets of the various longitudinal (LT) specimens and

transverse (TL) specimens are presented and compared in Figures 4, 5, and 6,

and in Appendices B. C and D. In Figure 4, all data for the six plate steels

tested are given, and in figures 5 and 6 are given the results for the three

head-plate steels and for the three shell -plate steels, respectively. The same general effects of orientation discussed above for individual data sets are observed to obtain for these combined data sets, and this supports the

validity of the practice of combining data sets for the purpose of making

comparisons of data taken from more than one individual data set.

11
Thus, results taken from the tables of Appendices B, C and D are given

in Table 4. This table shows that shelf-energy absorptien^yal ues for the

steel plates taken from tank cars of the four accidents^ " ' are about 67 and

41 ft-lb, respectively, for longitudinal and transverse specimens. For

transverse specimens, the 15 ft-lb and the 15- mil transition temperatures

average 9 to 24 F, but as is indicated by the data points on the figures 4B

and 4C, the scatter in the behavior is very wide, and these fracture criteria are not met even at 80 F in selected specimens taken from tank cars. The

50-percent SFA value for either longitudinal or transverse specimens is 68 F,

and here, too, the scatter in data taken on the six steels plotted on Figure

4A is very wide and is such that this criterion is not met even at 120 F for

selected data.

The data for head-plate specimens, given in Figure 5, vary more widely

than the data for shell-plate specimens, given in Figure 6. This wide

variance in test results of head-plate specimens gives rise to an unusually

shaped pair of curves in Figure 5A, where the SFA data is presented. The

analysis of longitudinal test results gives a curve of very steep slope while

that of transverse specimens gives a much more gentle slope; nevertheless,

the 50-percent SFA data for LT and TL head-plate specimens are similar, being

respectively 66 and 80. For the shell plate specimens these values are respectively 59 and 48 for LT and TL specimens.

For either the head-plate data or for the shell -plate data or for

contined head and shell data, the 15 ft-Tb and 15 mil TT values are similar

for LT and TL specimens, with the values for LT specimens being only slightly

lower in general than those for TL. As would be expected from the shapes of

the curves and from the earlier discussions, for higher values of either of

these fracture criteria the differences between the transition temperatures

for the two orientations would increase.

4.3 Anisotropy Indices for Plate Steels

Anisotropy of plate materials is assessed by an anisotropy index

defined here as the ratio of the maximum shelf-energy absorption in transverse

specimens of TL orientation to the maximum shelf-energy absorption of

longitudinal specimens of LT orientation. Then a value of 1 represents a completely isotropic plate and lower values represent the anisotropy which

may be present in partially cross-rolled or straight-away-rolled plate. This

index is given in Table 5 for each of three head-plate and three shell -pi ate

steels.

12
The data of this table show that the anisotropy index from CVN tests of

the head-plate steels averages 0.68, and that the index for the shell-plate

steels is 0.50. These indices indicate that each head plate was cross rolled more than any of the shell plates. The UT test results for one head and one

shell plate (both Callao) tend to confirm this finding, with indices of 0.65

and 0.51 for head and shell plates, respectively. Nevertheless, we note that

the axes for the head plates from Belle and Crescent City may deviate

substantially from true longitudinal and true transverse directions, and if

this is true for either of these steels, the index for that steel would be

increased with increasing amounts of misalignment from the true longitudinal

and transverse directions. Thus, it is concluded that the head plate of

Callao appears to have been cross rolled to a greater extent than were any of

the other plates (head or shell) and that the other two head plates (Belle and

C. City) may also have been cross rolled to a degree similar to that of the

Callao head plate.

The shelf-energy values for the six steels are plotted, for both LT and

TL specimens, as functions of their respective strength levels in Figure 15.

This plot shows that in general the shelf energy, whether longitudinal or transverse, decreases with increasing strength level for the six steels,

reflecting the strength level dependency of ductility reported for these

steels^^). Further, the two plots show that the relationship between

longitudinal and transverse shelf energy is relatively independent of strength

level; i.e., by comparing the two plots at various levels of strength, it is

observed that the energy of TL specimens is nearly half that of LT specimens,

with only a slight tendency for an increase in the ratio TL energy/LT energy

as strength level is increased. Thus, it is concluded that the anisotropy

index is not strength-level dependent, but that head-plate steels may have

been cross rolled to a greater extent than were the shell -pi ate steels.

4.4 Results for Individual Data Sets Representing Six Steel Plates

The 12 calculated curves representing six sets each of LT and TL test

results are given as Figures 7 and 8, respectively, for longitudinal and

transverse specimens taken from the six steel plates. A brief summary of

transition temperatures and upoer-shelf energy values taken from the

appendices of other reports(2"^)and from Appendix A of this report is given as Table 6.

13
Marked differences are observed for these various carbon-manganese

steels. Because these differences are generally similar for the longitudinal

and for the transverse specimens, only the longitudinal results will be

discussed in detail. Shelf-energy values vary from 46 to 81 for LT specimens

and from 25 to 55 for TL specimens. The 15-ft-lb TT values vary (for LT

specimens) from -47 to +92 F and the 15-mil TT values vary from -4;^ to +72 F. The 50-percent SFA values are much higher and they vary from -11 to 138 F.

The variation of shelf-energy values are shown in Figure 15 to roughly

follow the variation in strength levels of the steels, with the steels of

lower strength level having the highest shelf-energy levels. The effects of

the inclusion content and of the presence of vanadium on this behavior are discussed later in section 4.8.

It is noted in Figures 7 and 8 that the axes of the head-plate specimens

for Belle and Crescent City may deviate from true longitudinal and transverse

directions of the plate from which they are taken. If, in fact, the axis for

either steel does deviate substantially, then it would be expected that the

longitudinal values would fall below the trend line of Figure 15 and the

transverse value would fall above the trend line. These two conditions are not met for either steel, indicating that the nominal directions are not

substantially different from the true plate directions.

Except for the Callao head-plate (K-1), each of the TC128 steels tested

have lower TT values than do either of the two A212-B grades. The variable

microstructures of the Callao head plate, which had been hot formed and

stress relieved, are reflected in the relatively high transition temperatures

of this plate, as described and discussed in the findings report'^', and

they are illustrative of factors which can lead to departures from the

expected hot-rolled properties of plate steels. The attainment of the desired

fine-grained ferritic microstructure in the hot-formed plate is dependent upon

the use of an austeni tizing temperature in heating the plate for hot forming

that is high enough to obtain substantially homogeneous austeni te, but not so high that significant grain growth occurs, and upon a cooling rate during the

hot-forming operations that is at least as rapid as the air cooling of the

plate after rolling. In this instance, the relatively coarse-grained microstructure indicates that the plate had been heated to an austenitizing

temperature somewhat above the grain coarsening temperature for this steel.

Furthermore, in steels containing vanadium, as this was, the vanadium

carbides, which are difficult to dissolve in austenite, will normally be only

partially taken into solution at temperatures below the grain coarsening

temperature, and the resulting strength would normally be lower, and the

impact properties correspondingly better than those of the hot-rolled

14
product. In this instance, however, the high strength of this plate,

indicates that, at the presumably relatively high temperature to which it had

been heated for hot forming, significant amounts of vanadium carbides had been

dissolved in the austenite and had precipitated during cooling. The impact

transition temperatures of this plate are, thus, probably inferior to those

that would be expected in a hot-rolled plate, finished at a suitably low

temperature and hot rolled from the same heat of steel.

The steel with the lowest transition temperatures is the Belle sample, a TC128-A steel. This steel also has the finest ferrite G.S. Number (8.5) and a fine pearlite colony size, both of which may be attributed to the presence of

vanadium and the rolling practice. While the A212-B steels have low strength,

they also have coarser ferrite grain sizes (6.0 for the head plate and 7.0 for

the shell plate), and the pearlite colony size is coarse for both plates; the

head plate was not produced to fine-grain practice and it indeed has

transition temperatures that are higher than those of the shell plate, a result that is expected. The other steel not made to fine-grain practice is

Callao shell plate K-5; this steel has transition temperatures that are generally intermediate among the four TCI 28 steels tested. This result is

somewhat anomalous, as this steel would be expected to have comparatively high

transition temperatures; apparently, other processing factors for this steel are overriding the effect of deoxidation practice on the impact transition

temperatures. .. .the steel does, for example, have intermediate pearlite colony

size indicating that the finish rolling temperatures were relatively low for

this plate.

4.5 Comparison of Results of Combined Head and Combined Shell Data

The longitudinal (LT) and transverse (TL) test results for combined data

from the three head plates and from the three shell plates are presented in

Appendices C and D and as Figures 9 and 10, respectively, for LT and TL

specimens. A summary of these results is given as Table 7. The results

indicate that the CVN impact properties of the three head-plate steels are very similar to those of the shell-plate steels, but that the head-plate test

results are much more highly variable than those of the shell-plate steels.

This latter effect is apparent on the plots of the raw data, shown in the

figures. In assessing the high variability of results of the head-plate

tests, we note that the head-plate steels include a TC128-A steel which had

the lowest transition temperatures, and it includes the A212-B steel not

produced to fine-grain practice and this steel has the highest transition

temperatures. Because this latter steel was not produced to fine-grain

practice, it would be expected to have relatively high transition temperatures

compared to A212-B steels that were produced to fine-grain practice.

15
The third head-plate steel is a TC128-B steel that contained more than the

0.02 percent vanadium needed to qualify it as a grade A steel, and this steel

also has an unusually coarse microstructure in the part of the plate from

which the CVN specimens were taken. The three shell-plate steels are less

variable and they include an A212-B steel made to fine-grain practice, and two

TC128-B steels, one of which contains sufficient vanadium to qualify for grade

A and one of which was not made to fine-grain practice.

4,6 Comparison of Four TCI 28 Steels and Two A212-B Steels

The longitudinal (LT) and transverse (TL) test results for combine data

from the four TCI 28 steels and from two A212 steels are presented as Figure 11

for longitudinal (LT) specimens, as Figure 12 for transverse (TL) specimens,

and as Appendix F. A sumnary of these results is presented as Table 8.

The results indicate that the TC128 steels have lower but highly

variable transition temperatures and that the upper-shelf energy absorption

values of the A212-B steels are significantly higher than those of the TC128

steels.

For longitudinal specimens of the TC128 steels, the 15-ft-lb and 15-mil

TT values are respectively -5.7 and 3.9 F. Taking the TT values for both LT

and TL specimens into account, we note that the TT values of the two A212-B

steels are 42 F higher than those of the combined TC128 steels. The 50-percent

SFA TT values are much higher, but the difference between the two sets of

combined data averages 45 F. Thus, the differences between the two types of

steel are similarly large by various criteria and they are believed to be

significant.

The generally lower transition temperatures of the TC28 steels, as compared with the A212-B steels investigated, reflects primarliy the higher

managanese and lower carbon contents, and correspondingly higher

manganese-carbon ratios, of the TCI 28 steels which had a mean composition of

0.26 C and 1.27 Mn with a Mn/C ratio of 4.88, in contrast with the A212 steels

which had a mean composition of 0.30 C and 0.79 Mn and a Mn/C ratio of 2.63.

The relatively high transition temperatures reflect both their coarse ferrite

grains and their relatively large percentages of pearlite, which itself is due

to their higher levels of carbon. With its low manganese content, the ferrite

grain size of the hot-formed A212 steels is relatively large, particularly in

the heat which was not produced to a "fine grain" practice, and it is

therefore necessary to use a relatively high carbon content to meet the

strength requirements.

16
The plots of the data on figures 11 and 12 indicate that the variability

in test results for the four TC128 steels is very large and much larger than

that for the two A212-B steels tested, reflecting that there are significant

differences in the transition temperatures among the TCI 28 steels tested.

These differences appear to reflect primarily differences in strength, with

the B-head steel from the Belle accident having the lowest 15-foot-pound

transition temperature of -46.5 at a tensile strength of 84 Ksi, which is just

above the minimum requirement, and the South Byron shell plate having a transition temperature of 18 F at a tensile strength of 103 Ksi, which is just

above the maximum level of the specification. The Callao shell plate,

although it was made from a heat which was not produced to a "fine grain"

practice and had a somewhat larger ferrite grain size than the other TCI 28

steels, still has a reasonable low transition temperature of -5 F at its

realatively low tensile strength of 87 Ksi.

Another factor which must be taken into consideration in evaluating

these findings, although specific data is apparently not available, is the

fact that these tests were made on material which had been stress relieved

following a forming operation, so that the properties may differ from those

of the original hot-rolled plates. Variations in the stress-relieving

treatment could significantly affect the properties, primarily because of the

possible effect of the tempering on the strength. Thus, among these TC128

steels, the steels, with vanadium would, if the carbon content is not

correspondingly decreased, be expected to be higher in strength in the

hot-rolled condition than those without vanadium, because of the strength

increment from the vanadium carbide precipitation. The South Byron shell

steel which contained vanadium and had the highest strength of the TC128

plates tested, is illustrative of this expected effect of vanadium. The Belle

B-head steel which also contained vanadium, however, had the lowest strength

among the TC128 plates, and the low strength of this plate, therefore,

presumably results from tempering at a relatively high temperature in the

stress relieving operation.

The higher values of shelf energy of the two A212-B steels may relate to

their relative cleanliness; these two steels are the only steels of those

tested that have only moderate levels of inclusion content.

17
4.7 Results of Data Combined on the Basis of the Grade of Steel

The six steels were produced according to three grades of steel:

TC128-A, TC128-B and A212-B. However, we note that the principal difference

between the two TCI 28 grades is the Grade A requirement of a minimum vanadium

content of 0.02 percent by weight. Thus, for the purpose of comparison of the

six steels according to the grade to which the steels were produced, the

steels have been grouped into four classes with the three TC128-B steels being

divided into two groups, one group with two steels containing more than the

0.02-percent vanadium and one group of one steel without the vanadium. The

plots of the data and calculational results for these four classes of steels are given as Figures 13 and 14 and as Appendix G. A summary of these results

is presented as Table 9.

The upper-shelf energy-absorption values indicate that the steels rank

as follows, beginning with the highest values: two A212-B steels, one TC128-B

steel without vanadium, one TC128-A steel, and two TC128-B steels that contain

more than 0.02-percent vanadium: The inclusion content ranks^ ' for these four

classes of steels are, respectively, as follows: Rank 1.0 (ave.). Rank 2.0,

Rank 3.0, and Rank 2.5 (ave.). The results indicate that lowering inclusion

content can be helpful to improved upper-shelf energy absorption, but that

other factors may also affect upper-shelf energy levels.

On the basis of transition temperatures, the steel classes rank as follows, beginning with the lowest TT values: TC128-A, TC128-B without

vanadium, TC128-B with vanadium, and A212-B. These differences are related to

differences in the ferrite grain size and to differences in the contents of

principally carbon, manganese and phosphorous of these steels.

On comparing steels on the basis of their vanadium content, it is noted

that the one TC128-B steel without vanadium has 15-mil and 15-ft-lb transition

temperatures that are about 22 F below those of the two TC128-B steels with

vanadium, but the 50-percent SFA TT values for the steel without vanadium are about the same as the values for the two steels with vanadium, indicating that

the apparent differences attributable to vanadium may be marginal, and that

the effect of vanadium on transition temperatures in TC128-B steels is not

firmly established by the limited available data. However, the TCI 28 steels

have transition temperatures that are superior to those of the A212-B steels,

a fact which will be discussed later.

18
4.8 Upper-Shelf Energy Absorption

The upper-shelf energy-absorption values for the six carbon-manganese

steels tested for these investigations are plotted as functions of the

ultimate tensile strength (UTS) in Figure 15 and as functions of the yield

strength (YS) in Figure 16. The correlation with UTS is reasonably good. The

correlation with YS is based not upon values for only carbon-managanesegx

steels, but upon val ues'obtai ned for a wide variety of steels reported^

from a major steel producer's general findings. This YS correlation is

poor for the steels investigated, and it indicates that the presence of

vanadium and increased inclusion content levels may tend to decrease the

shelf-energy of these steels. Shelf energy of the six plate steels and the one weldment investigated are much more strongly affected by increases in YS

than are the various steels included^) in the solid trend line of Figure 16.

The dotted line of Figure 16 representing six steels tested, shows that for

these steels, with increasing YS values from 47 to 70 the upper-shelf

energy-absorption values decrease sharply from 81 to 46 ft-lb. It is noted

that the three steels with the lowest shelf-enerqy values each contain

vanadium. One is a TC128-A steel (Belle, B head) with a high inclusion

content and the other two are TC128-B steels (Callao K-1 A-head and the S.

Byron shell plate). These later two have the lowest shelf-energy values of

the six steels tested and their inclusion contents are intermediate (for K-1)

and high (for S. Byron). The other three steels do not contain vanadium and

inclusion contents are intermediate (for the TC128-B steel) or moderate (for

the A212-B steels) and they do not depart greatly from the published trend

line. These results indicate that increased inclusion content levels and the

presence of vanadium tend to decrease upper-shelf energy-absorption values.

Crack initiation and propagation at temperatures on the upper shelf occur by a fracture mode known as dimpled rupture or normal rupture, which

proceeds as a result of the progressive formation and coalescence of voids at or ahead of the crack tip. As inclusions are the main source of void

initiation in these steels, it is apparent that the inclusion content will be

a predominant factor effecting this behavior. Further, as the predominant

inclusion in each of these steels is manganese sulfide and as the rolling

practice for each of the plates is similar, although the head-plate steels seem to have received more cross rolling than the shell -plate steels, it is

expected that the shelf-energy absorption of the steels will decrease with

increases in the inclusion content, due to the increased number of initiation

sites present in the steels with higher inclusion contents.

19
Furthermore, on a microscopic scale, the void coalescence process

proceeds by the necking and rupture in tension of small elemental volumes

lying along, or ahead of the crack front, which is analogous to the process,

on a macro-scale which leads to the failure in the tensile test. The

susceptibility to failure of this type is therefore increased by (1)

a high yield stress which leads to a high flow stress for the initiation

of these plastic processes, and (2) a low strain hardening capacity

or a low uniform elongation prior to the necking which leads to the rupture.

4,9 Energy Absorption at Various Service Temperatures

In table 10, CVN energy-absorption values are given for various service

temperatures from -40 to +80 F, in increments of 20 F. Values are given both

for the individual data sets of each of the six plates tested and for combined

data for each of the three categories: three head-plates, three shell plates,

and all six plates. These calculational results indicate that, in general,

the transverse (TL) values of energy absorption for a given temperature are slightly lower than the longitudinal (LT) values; at high values of energy

absorption the TL values are much less than the LT values. These findings hold

true for the individual data sets as well as for the combined data sets,

A table of this type, which is readily prepared from the appendices of

this report and previous reports(^"^) , is useful in making assessments the

probability of obtaining a given level of energy absorption for various

temperatures of service. For example, for transverse specimens, a 15-ft-lb

criteria is met at 80 F by five of the six steels tested, at 60 F and at 40 F by three steels, at 20 F and 0 F by two steels and at -20 and -40 F by only

one steel

The results of the combined data sets are given in comparison with

averaged results of the individual data sets of each of the three categories.

For any service temperature, the results of combined data analyses do not

differ by more than about 5 ft-lb from those of the averaged data for

individual sets, and generally, the agreement is within about 2 ft-lb at any

given temperature. If the energy-absorption values were to include statistical

limits, the combined data sets would prove to be most useful for making

probability statements, but statistical limits of the type needed have not yet

been incorporated into the computer method used for these calculations.

20
4.10 Behavior of Weldments of TC128-B Steel

CVN specimens of weld-metal and weld heat-affected-zone (HAZ) regions

were taken from samples of steel taken from a tank car designated GATX 94451

that failed in Callao, Mo. The weld-metal specimens represent shell -shell

weldments of TC128-B steel of this tank car. The specimens are of two

orientations, longitudinal (LT) and transverse (TL), as defined in Figure 1,

and they were taken respectively from Callao plate samples K-11 and K-8. The

weld-HAZ specimens are of the TL orientation, and they represent weld HAZ

regions of the "A" head plate and of shell course nunt>er 1; they were taken,

respectively, from Callao plate samples K-2 and K-8.

Test results for the weld-metal and the weld-HAZ regions are respectively presented in the Callao report^''/ (as Figures 37 and 38 and as Appendices F and G). A brief summary of these findings is presented here as table 11, where along with these results, results are presented for the

unaffected base metal of the steels for which weldment data are given.

The results indicate that the impact characteristics of the weldments

tested are much more favorable than those of the base metals. In addition,

the results of the weld-metal tests indicate that the longitudinal and the

transverse weld-metal results are similarly favorable and the results of the

weld-HAZ tests are even better. The head-plate and the shell-plate steels

have 15-ft-lb TT values of 64 and 3 F, whereas the weld-metal values average

-37 F and those of the HAZ regions average -48 F. The upper-shelf values for

the head plate are +46 ft-lb for the unaffected base metal and +49 ft-lb for

the weld-HAZ region of this plate, and those of the shell plate are 38 and 45

ft-lb, respectively, for the base metal and the weld-HAZ region. Upper-shelf

energy of the weld metal is most favorable, being about 67 ft-lb. Thus, the

transition temperature values and the shelf-energy absorption values of the

weld-metal (LT and TL) specimens, and of the HAZ specimens of both the

head-plate and the shell -pi ate tests, are believed to reflect good welding

practice*.

We suspect that the CVN values obtained for the HAZ region might not

be representative of the behavior of the plate in service. This suspicion

is based on our finding that the shape of the HAZ region precludes the

placement of the notch uniformly along the coarse-grained region of the HAZ.

(This region is considered to be the most brittle region in many weldments).

For this reason it is believed that the DT test might be a more suitable test

method for determining the impact characteristics of the HAZ of weldments of

plate material of thickness levels similar to those of the plate materials

tested in this work. This belief is based on the presumption that while the

problem of the initial placement of the notch would not be alleviated for the

DT test, the crack path in the DT test is much longer than in the CV test.

Then, perhaps as crack propagation progresses, the crack front would seek

and follow the most brittle region along a weldment in a manner similar to

that which would obtain in the fracture along a weldment in a large plate

in service.

21
4.11 Dynamic-Tear Tests

As was shown in table 1, dynamic-tear (DT) tests were conducted on one head and one shell plate of AAR TC128-B steels taken from the

Callao accident. Both longitudinal (LT) and transverse (TL) specimens

were tested over the range of temperatures from -50 to +1300 F. Thus,

some of these tests were conducted at temperatures similar to those used

in the CVN tests of these steels, and the results of these tests can be

used to compare the behavior of impact loading under the two types of

test conditions. In addition, the results of the elevated-temperature

tests of DT specimens provide preliminary estimates of the behavior of

the two steels tested under short- time exposure (about 25 minutes) to air at

temperatures likely to be encountered in a fire. Although the significance

of the results of elevated-temperature impact tests has not been clearly

established, they indicate that the critical flaw size for rapid propagation of a crack in a vessel at temperatures near 1050 F is smaller than that at lower

temperatures. The results of these various DT tests were presented in

the Callao report^^), (as Figures 34 to 37, 39, and 40, and Appendices B through E)« Only Sunmary tables are presented here.

4.11.1 Ambient-Temperature Results

A comparison of the results of DT and CVN tests, given in Tables 12 and

13, indicates that the DT test gives higher transition temperatures but lower

values of upper-shelf energy- per- unit area. In addition, it is noted that the

nil -ductility- transition (NOT) temperature can be established from DT test

results, and the NDT temperature is about 40 F for the head-plate steel tested

and about 34 F for the shell-plate steel tested.*

As shown in Table 12, DT test results show similar TT values for

50-percent SFA and 50-percent of maximum energy absorption: for the head-plate

steel these transition temperatures are respectively 90 and 82 F, and for the

shell -plate steel they average 92 and 87 F.

* The tank car from which these samples were taken apparently failed upon

impact with a part of a bridge and it is estimated that the temperature

of the steel of the tank car was about 15°F when this occurred. Steels

with NDT temperatures at and above this temperature would be expected to

fail in a fast, brittle-fracture mode under severe impact conditions.

Thus, brittle failure was virtually assured for these steels under severe impact conditions at 15°F. However, the method by which these NDT

temperatures were determined are non-standard methods and the NDT values

of these particular steels are therefore somewhat open to question.

22
A comparison of DT and CVN test results must take into account the

previously discussed microstructural heterogeneity of the head-plate steel.

This is particularly important because the CVN specimens were taken from one side of the plate thickness whereas the UT specimens were full plate

thickness.

For the shell plate, the expected difference between TT values for

results of LT and TL specimens is shown in the TT values given in Table 12 for

each of two fracture criteria, one based on energy absorption and one based on SFA. For the head-plate tests, these differences are much larger than

expected; this point is elaborated upon below.

To facilitate conparisons of DT and CVN tests results (i.e. transition

temperatures) an arbitrary energy level was selected for the DT results that

are to be compared with 15-ft-lb CVN results. This energy level is called the

DTEE, dynamic- tear equivalent energy. DTEE is a calculated energy level that

is the same fraction of the DT upper-shelf energy as the fractional energy

level that 15-ft-lb represents for the CVN upper-shelf energy level.

For the head plate, the difference between the transition temperatures

of LT and TL orientations for CVN specimens iS/as expected, but it is very

large for the DT test specimens. It is noted^ ' that the transition

temperatures of longitudinal DT (HDTL) specimens occur at unexpectedly low

values in DT tests of this headrplate steel. These low values of transition

temperatures are attributed(^»^^ to microstructural inhomogenei ty in the DT

test specimens of this head-plate steel.

Excluding the anomalous results of the longitudinal head-plate

specimens, it is observed that, for both fracture criteria given, transition

temperatures of DT tests average about 45 F higher than those of CVN tests,

indicating that, for these steels, the DT test provides more conservative

estimates of the impact behavior.

When compared on the basis of energy-per-unit area, Table 13 indicates

that greater energy is required for shear fracture of DT specimens than for

CVN specimens. For all results, except those for the anomalous longitudinal

head-plate specimens, the DT values are less than twice those of the CVN

values; for the longitudinal head-plate specimens, the DT value is slightly

more than twice those of the CVN value. These results indicate that the

CVN test gives more conservative estimates of upper-shelf energy required for

fracture.

4.11.2 Anisotropy Indices for Plate Steels

As discussed earlier, anisotropy of plate materials may be assessed by an anisotropy index defined here as the ratio of the maximum shelf-energy

absorption in transverse specimens of TL orientation to the maximum

shelf-energy absorption of longitudinal specimens of LT orientation. This

index is tabulated below for the head-plate and shell-plate steels.

Anisotropy Index

Head Plate K-1 Shell Plate K-5

38/54 = .70 38/75 = .51

420/650 = .65 377/746 = .51

It is apparent from the table that the head plate is less anisotropic

than the shell plate. However, the head plate was not fully cross rolled, as its indices are less than one. The indices from DT tests compare favorably

with those from CVN tests. The DT results for the head plate indicate a slightly lower index than expected, but this too might be related to the

anomalous effects attributed above to microstructural differences between the

longitudinal and transverse DT specimens.

4.11.3 Elevated-Temperature Test Results

The results of elevated-temperature DT tests show that at temperatures

of from the beginning of the upper shelf to 1300 F the fracture appearance is

100-percent shear, but the energy-absorption values are variable and the

energy-absorption plots have minimum values at temperatures near 1050 F. These findings were presented as Figures 39 and 40 of reference 4 and they are summarized here in Table 12.

For each of the four sets of tests conducted, a minimum value of energy

absorption occurs in the range of temperatures from 850 to 1100 F, depending

on the steel and the specimen orientations. For three of these sets, the

minima fall within a narrow range of 1000-1 100°F. The fourth set, HDTL,

has a minimum at 850°F, which may be misleading because a measurement was not

taken at 1100°F.

24
The results of tests of transverse head-plate specimens indicate that

the magnitude of the decrease in upper-shelf energy-absorption values at

elevated temperatures can be greater than 50-percent of the maximum energy

absorption that is obtained over the usual range of impact test temperatures.

Although the significance of these results has not been clearly established,

they indicate that TC128-B steels can be embrittled at elevated temperatures

in a manner that permits propagation of a crack at temperatures near 1050 F to occur with relatively small levels of energy absorption. The cause of this

embrittlement has not been established and it is uncertain as to whether these

results may be relevant to the slow- deformation strength or to the

creep-rupture properties at these elevated temperatures.

5. SUMMARY

Results obtained from impact tests of two plates of ASTM A212 steel,

four plates of AAR TC128 steel, and two weldments of TC128 steel can be

summarized as follows:

5.1 Anisotropy of the impact properties of the steels tested was three

dimensional. The upper-shelf values and the transition temperature (TT)

values were affected by orientation of specimen and notch, but the 50-percent

SFA value was not affected.

5.1.1 For the six orientations tested, upper-shelf values of energy

absorption and lateral expansion varied widely with orientation and tended to

decrease in the order LS, LT, TS, TL, ST, SL; the corresponding values for

15-mil and 15-ft-lb transition temperatures also varied widely and they tended

to be in inverse order to the level of their upper-shelf values.

5.1.2 For the six steels tested, SFA values are not greatly affected by

orientation of specimen and notch; the 50-percent SFA criteria is shown to

have an invariant character for all orientations tested for a given steel with

the mean value for various orientations being generally within 10 F of the

value for any individual orientation.

5.1.3 The 50-percent SFA TT value for combined data of the six steels was 68 F for either longitudinal or transverse specimens, but this fracture

criterion varied widely for the six individual steels tested, as for example,

for longitudinal (LT) specimens the values range from -11 to +138 F.

25
5.1.4 The temperature at which 50-percent SFA obtains was approximately the same as the temperature at which 50-percent of maximum energy absorption

obtains. This was true for any individual data set as well as for any

combined data set. Consequently, the 50-percent SFA criteria was shown to be

generally satisfied at a considerably higher temperature than the temperatures

at which the 15-mil or 15-ft-lb criteria were satisfied.

5.2 For a given orientation of specimen and notch, upper-shelf energyabsorption values for the six steel plates varied widely. The results

indicated that shelf-energy absorption tended to decrease with increases in

the inclusion content and the strength level of the steels, with this strength

level dependency reflecting the strength level dependency of ductility. In addition, the shelf-energy absorption values for LT and TL specimens indicated

that the head plates were cross rolled to a greater extent than were the shell

plates.

5.2.1 Shelf-energy absorption values for the combined data from the six steel

plates were about 67 and 41 ft-lb, respectively, for longitudinal (LT) and

transverse (TL) specimens.

5.2.2 Shelf-energy absorption values for the six steels varied widely: For

longitudinal (LT) specimens they ranged from 46 to 81 ft-lb, and for

transverse specimens they ranged from 25 to 55 ft-lb.

5.2.3 When compared with a published trend line, three of the six steels

tested had relatively low values of shelf-energy absorption for their

respective yield-strength levels. These three steels were TC128-A and -B

steels that contain vanadium and have either high or intermediate inclusion

contents. These results indicate that increased inclusion content levels and

the strengthening effect due to vanadium tended to sharply decrease

shelf-energy absorption values.

5.2.4 The anisotropy index values derived from shelf-energy levels of CVN and

UT impact tests indicated that each of the three head-plate steels were cross rolled to a greater extent than were any of the shell -plate steels. The

indices derived from DT tests compared favorably with those derived from CVN

tests

5.3 Transition temperatures of the six steels tested varied widely, due to

wide differences in the ferrite grain size and the contents of carbon,

manganese, and phosphorous. Only one of these steels was produced to TC128-A

specifications and it had fine ferrite grains and a fine pearlite colony size,

both of which may be attributed to the presence of vanadium and the rolling

practice. This steel had the lowest transition temperatures of the six steels

tested. Transition temperatures of the three steels producted to TC128-B

specifications were lower than those of the A212-B steels, and the A212-B

steel produced to fine-grain practice had lower TT values than the one that

was not produced to fine-grain practice.

26
5.3.1 Transition temperatures of the combined data for the six steels tested

in both LT and TL orientations averaged 14 and 20 F, respectively for the

15-ft-lb and 15-mil criteria.

5.3.2 Transition temperatures for the six individual data sets of the six

plates tested varied widely, especially those for the head-plate steels. The

15-ft-lb (LT) values ranged from -47 to +92 F for the head plates and from

-5 to +32 F for the shell plates, while the values for the combined data were similar, being +13 and +7 F respectively for the head plates and the

shell plates.

5.3.3 The six steels tested were catagorized into four classes of steels.

These classes can be ranked on the basis of transition temperature, beginning

with the class of lowest TT values: TC128-A, TC128-B without vanadium, TC128-B

with vanadium, and A212-B.

5.4 Results from combined data sets indicate that the two A212-B steels

tested had higher values of upper-shelf energy absorption but inferior

(higher) TT values when compared with the values for the four TC128 steels

tested. In addition, the variability in the test results for the four

TCI 28 steels was large and much larger than that for the two A212-B steels.

The higher values of shelf energy of the two A212-B steels may be attributable

to their cleanliness. Their relatively high TT values may be attributed to

comparatively less favorably levels of carbon to manganese when compared with

that of the TCI 28 steels.

5.5 The results of CVN impact tests of specimens taken from weldments of

TC128-B steels indicated that the impact characteristic of the weldments

tested are much more favorable than those of the base metals of these welded

steel plates. For example, the 15 ft-lb TT values of the steels averaged

38 F (for TL specimens) whereas those of the weld metal were -37 F and those

of the weld-HAZ region tests (TL) averaged -48 F. The transition temperatures

and the shelf-energy absorption values of the weldments tested were believed

to reflect good welding practice.

5.6 A comparison of results of DT and CVN tests results for a head-plate

steel and a shell -plate steel indicated that the DT test gives more conservative estimates (by about 45 F) of transition temperatures and the CVN

test gives more conservative estimates (by a factor of 1/2) of the upper-shelf

energy-absorption per unit area. However, for the Callao head plate (k-1)

this relationship between the transition temperatures as determined by the

two test methods was not observed to hold, and this finding was attributed to

the microstructural variability of this head plate, which had fine ferrite on one side and coarse ferrite on the other side of the plate thickness, and to

the fact that the CVN specimens were taken only from the coarse-grained

half of the thickness of this plate, whereas the DT specimens represented the

full thickness.

27
5.7 The results of DT tests conducted at elevated temperatures indicated

that upper-shelf energy-absorption values for two TC128-B steels varied

with temperature (for 25 minute exposure time), and at temperatures near

1050 F the energy-absorption value can be less than 50-percent of the value

measured at temperatures near the ambient temperature. The results indicated

that the impact toughness of the steel at temperatures above that of the

ambient air, can be significantly decreased by elevated- temperature

embrittlement which occurs by a mechanism that has not been clarified.

6. CONCLUSIONS

6.1 The variability of impact properties of steels used as plate material in

tank cars and the factors that contribute to this variability should be given

consideration in specifications for steels used for plate material of tank cars. Impact properties of these steels are principally governed by ferrite

grain size and the levels of carbon, manganese, and phosphorous, and the

content of inclusions in these steels.

Transition temperatures obtained from CVN tests of six plate steels

taken from four failed tank cars indicate that the variance of TT values of

these steels is large, with 15-ft-lb CVN longitudinal-specimen transition

temperatures that range from -47 to +92 F. This wide variability of

transition temperatures is variously attributable to variations in such

factors as the levels of carbon, manganese, and phosphorous, and the ferrite

grain size which itself is affected by the presence of vanadium, the

deoxidation practice, as well as other factors that can be governed by the

specification to which the steel is produced.

Upper-shelf energy-absorption values obtained from these CVN tests

indicate that the six steels tested vary widely in ability to resist failure

at temperatures at which the shear mode predominates. Various factors affect

this behavior and in the steels tested the upper-shelf energy-absorption value

appears to decrease with high inclusion content, which is related to the . sulfur content of the steel, and with increased strength level of the steel,

which is affected by various compositional and processing factors.

6.2 The results of CVN impact tests of six steel plates and those of DT

tests of two steel plates indicate that these steels taken from failed tank cars have relatively high transition temperatures and poor resistance to

failure under impact loading conditions. The relatively high transition

temperatures of these steels is demonstrated by the finding that a modest

fracture criterion of 15-ft-lb energy absorption in transverse specimens was satisfied by only one (of six tested) steel at temperatures of -20 to -40 F and by only three steels at temperatures of +40 and +60 F. The relatively

28
poor resistance to failure under impact loading and the tendency for rapid,

brittle crack propagation at cormon service temperatures is supported by the

findings of the CVN and DT test results. The combined data for six plate

steels indicate that a 15-ft-lb CVN criterion was satisfied at 9 and 19 F,

respectively, for longitudinal and transverse specimens, but that the variance

was large: For longitudinal specimens of the six individual steels, these

temperatures ranged from -47 to +92 F. Further, for one of these steels (the

Callao shell-plate K-5), the 15 ft-lb transition temperatures were -5 and +3

F, respectively, for longitudinal and transverse specimens. The nil ductility

temperature for this steel, as estimated from the results of DT tests, is 30

and 38 F, respectively, for longitudinal and transverse specimens, indicating

that at many service temperatures this steel would have very little resistance

to impact loads and that failure would tend to be brittle with rapid crack

propagation.

With these considerations in mind, it would be desirable to use steels

with (1) greater resistance to brittle failure under impact loading conditions

and (2) greater resistance to rapid crack propagation under normal and abusive

service conditions. The need for steels with such improved properties should

be assessed.

6.3 The need for improved impact properties for head-plate steels and

shell-plate steels should be determined independently, since some of the

design alternatives might involve improved properties for the head plates,

the shell plates, or both.

The results of impact tests of three head-plate steels and those of

three shell -plate steels indicate that impact characteristics of the

head-plate steels tested were similar to those of the shell-plate steels

tested but that the impact properties of the head-plates tested were much more

highly variable than those of the shell-plates tested. Average transition

temperatures of three head plates are 13 and 33 F, respectively, for

longitudinal and transverse CVN specimens: Those for three shell plates are 7 and 23 F, respectively. The 15 ft-lb TT values for longitudinal specimens cover a wide range from -47 to +92 F for the head plates and a narrower range

from -5 to +32 F for the shell plates.

6.4 The anisotropy of impact properties of steels used as the plate material

of tank cars should be assessed in relation to the design of tank cars, and

this should be done with the understanding that circumferencial failure of

tank cars is promoted by the current design. The anisotropy of these steels

tends to be such that upper-shelf energy absorption and transition

temperatures are affected by specimen orientation. Energy absorption values

tend to decrease in the following order of specimen orientations: LS, LT, TS,

TL, ST, SL, and the corresponding transition temperature values tend to be in

1

29
the inverse order to that of the shelf-energy absorption values for various

orientations. Thus, longitudinal specimens tend to have the highest

upper-shelf energy absorption and the lowest transition temperatures, and

transverse specimens have significantly poorer impact properties. Hence,

failure is promoted in the direction of final rolling of the plate— this was shown to be especially true for the shell-plate steels but it is also

true for the head-plate steels tested. The result is that fracture in the

circumferential direction of the tank car is promoted in shell plates and this can and does sometimes^^'lead to rocketing of large tank car sections.

6.5 The elevated- temperature embrittlement demonstrated by TC128-B steel

should be studied further and the results should be interfaced with the

elevated-temperature requirements of steels used for plate materials of tank cars. The results of elevated- temperature DT impact tests indicate that

upper-shelf energy-absorption values are a function of temperature and that,

at temperatures near 1050 F, the energy absorption in DT tests can be less

than 50-percent of the value measured at temperatures slightly above the

temperature of ambient air. These results indicate that at these temperatures

an elevated-temperature embrittlement of the steel occurs by a mechanism

that has not yet been established. The decrement in the energy-absorption

capacity at elevated temperatures has been observed for two TC128-B steel

plates tested after exposure at various temperatures for about 25 minutes in

air. The effect of time at temperature on this decrement is not now known,

and the susceptibility of MR TC128-A steels or that of ASTM A212-B steels or other steels used as plate materials of tank cars is not known nor is the most

important effect of strain rate known. Thus the significance of this

embrittlement is now open to question.

(a) The orientation code for these head-plate HAZ specimens applies

to the direction of welding. The angle between the specimen

axis and the principal rolling direction of the plate is about

45°, and thus these results would be expected to be intermediate

between those that would obtain for true longitudinal and true

transverse . specimens

An overview of the results and metallurgical analyses of the findin<t£

of impact tests conducted at the National Bureau of Standards on samples (pi

tank-car materials submitted by the Federal Railroad Administration is

presented. The submitted samples were taken from tank cars which had beeifi

involved in service accidents during the period January 197 C to January

1971. One of these tank cars had been fabricated from ASTf*^ A212 steel anc^

the rem.aining four tank cars from AAR TC128 steels

As a data compilation detailing the characteristics of tank car steil

this report can serve as a basis for further analysis and as an example

how impact data can be handled to derive a general understanding of the

fracture characteristics of these materials. The data do allov,' a compari^c

of longitudinal, transverse, and short transverse properties in these pla-(:e

and they illustrate impact toughness trends as they relate to chemical

composition, grain size "and cleanliness of the specific plates studied.

Further, they illustrate the comparative results that are expected from

Charpy-V--notch tests vis-a-vis those from Dynamic Tear tests for the steeds

tested. When these various findings on the impact properties and on the

metallurgical factors affecting them are considered along with the observed

behaviors of these materials in service, recommendations as to approaches

to improved materials and improved specifications for such materials can ipt

formulated i 17. KE\ U0Rl"'5' (six to twelve entries; alphabetical order, capitalize only the first letter of the first key word unless a proper
