| NEW YORK, June 1.-THE great
steel industry, struggling along at about
40 per cent Of its capacity, feels pain
| fully ike q pauper these days, but it
stu has young prince in the family.
The production Of the new non-cor-
roding alloys Is one phase of the indus
try that has continued to make marked
progress during these hard times.
Harry e. Sheldon, president Of the
Allegheny Steel Co., told the Associated
Press today that it Is estimated that
production Of these alloys in the half
dozen mills making them in this coun-
try has probably doubled in the past
Is months.
While tonnages are still compare
lively small" he explained, the dollar
volume Is fairly substantial, as the nom
corroding alloys are high-priced."
Becomes Specially Business.
Mr.. Sheldon. said great strides have
been made in fabricating these alloys
in the past two or three years, although
there are still difficulties to be over
come.
THE steel Industry" he added, els be-
coming a business in speciality steels
The engineer tells the steel mill what
he wants the material to do-the
strains 1t must undergo, the tempera-
influences present, the fabricating nee
essary-and the metallurgists at the
mill see that he gets a material espe-
cially adapted to fill all the require
ments
1.-The metallurgy Of steel and its al
Toys has progressed far in the past few
years. 1t Is strictly in keeping with
the present tightening up against waste
all along the line that the knowledge
4va
be applied in order that the greatest
possible degree Of efficiency may be at
tanned.
New applications for the chromium
and nickel steel and iron alloy group
are being found constantly in scores Of
industries"
Mr.. Sheldon pointed out that there
are various formulas designed for spe-
cific uses, but that the best known had
become the so-called "18 and 8" alloy,
made under various trade names.
The dairymen were the first to adopt
this non-corrosive metal, and were fol-
lowed by other food industries. The
metal won its way through its resist
ence to food acids and cleaning COM
pounds. The materials exceptional
strength, however, soon appealed to the
petroleum industry, where it was EN-
ployed in gasoline cracking processes.
Other Formulas Used.
1t has since come into use in various
chemical industries. The metal has re-
Gently been used extensively for both
ornamental and structural purposes by
architects. The motor and aviation in
dustries have also become users.
Other formulas Of the group have
made similar progress. The IL to Is
per cent chromium iron is being used
for turbine blades, internal combustion
engines, furnace parts and various min
ing uses. A formula containing high
er percentage Of chromium is used in
large quantities in nitric acid plants.
One formula, containing IS to 80 per
cent chromium, resists oxidation Up to a
temperature of also degrees Fahrenheit.
A more malleable alloy for similar pur-
poses contains substantial portion Of
nickel in addition to a large part Of
chromium.
