Foreword 
 
Development of the East African Standards has been necessitated by the need for harmonizing requirements governing quality of products and services in East Africa. It is envisaged that through 
harmonized standardization, trade barriers which are encountered when goods and services are 
exchanged within the Community will be removed.   
In order to achieve this objective, the Partner States in the Community through their National Bureaux 
of Standards, have established an East African Standards Committee.  
The Committee is composed of representatives of the National Standards B odies in Partner States, 
together with the representatives from the private sectors and consumer organizations. Draft East 
African Standards are circulated to stakeholders through the National Standards Bodies in the Partner 
States. The comments received are discussed and incorporated before finalization of standards, in accordance with the procedures of the Community.  
East African Standards are subject to review, to keep pace with technological advances. Users of the 
East African Standards are therefore expected to ensu re that they always have the latest versions of 
the standards they are implementing.

Hot-rolled steel sheet of high  yield stress structural quality  
 
 
1 Scope  
 
1.1 This East African Standard applies to hot-ro lled steel sheet of high yield stress structural 
quality in the grades and classes listed in Tables 1 and 2, with the use of microalloying elements. The 
product is intended for structural purposes where particular mechanical properties are required. It is 
generally used in the delivered condition and is inte nded for bolted, riveted or welded structures. 
 
Because of the combination of higher strength and microalloy composition, it is possible to obtain 
savings in mass along with better formability and we ldability as compared with steel sheet without 
microalloying elements. The product is produc ed on a wide strip mill, not a plate mill. 
 1.2 This product is commonly produced in thicknesses from 1.6 mm to 6 mm and widths of 600 
mm and over, in coils and cut lengths. 
 1.3 Hot-rolled sheet less than 600 mm wide may be slit from wide sheet and considered as sheet. 
 
NOTE Hot-rolled sheet up to but not including 3 mm in thickness is commonly known as “sheet”. Hot-rolled sheet 3 mm and 
over in thickness is commonly known as either “sheet” or “plate”. 
 
1.4 This East African Standard does not cover steel intended for boilers or pressure vessels, 
steels designated as commercial quality or draw ing qualities (ISO 3573, Hot-rolled carbon steel sheet 
of commercial and drawing qualities), steels to be rerolled to cold-reducing products, steels designated as weathering steels, having increased atmospheric corrosion resistance or steels having 
improved formability properties compared with those in this document. 
 
2 Normative reference 
 The following normative document contains provisions which, through reference in this text, constitute 
provisions of this East African Standard. For dated references, subsequent amendments to, or revisions of, this publication do not apply. However, parties to agreements based on this East African 
Standard are encouraged to investigate the possibility of applying the most recent edition of the 
normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid 
International Standards. 
 ISO 6892:1998, Metallic materials — Tensile testing at ambient temperature . 
 
3 Terms and definitions 
 
For the purposes of this East African Standard, the following terms and definitions apply. 
 
3.1 
microalloying elements 
elements, such as niobium, vanadium, titanium, etc., added singly or in combination to obtain higher 
strength levels combined with better formability,  weldability and toughness as compared to non-
alloyed steel produced to equivalent strength levels 
 
3.2 
hot-rolled steel sheet 
product obtained by rolling heated steel through a co ntinuous-type or reversing-type wide strip mill to 
the required sheet thickness the product having a surface covered with oxide or scale resulting from the hot rolling operation EAST AFRICAN STANDARD 
STANDARD FOR PUBLIC REVIEWEAS 415:2005  
2 © EAC 2005 — All rights reserved 3.3 
hot-rolled descaled steel sheet 
hot-rolled steel sheet from which oxide or scale has been removed, commonly by pickling in an acid 
solution 
 
NOTE Descaling may also be performed by mechanical means such as grit blasting. Some changes in properties may result 
from descaling. 
 
3.4 
edges 
 
3.4.1 mill edge 
normal edge without any definite contour produced in hot rolling 
 
NOTE Mill edges may contain some irregularities such as cracked or torn edges or thin (feathered) edges. 
 
3.4.2 sheared edge 
normal edge obtained by shearing, slit ting or trimming a mill edge product 
 
NOTE Normal processing does not necessarily provide a definite positioning of the slitting burr. 
 
3.5 aluminum killed 
steel which has been deoxidized with aluminum sufficient to prevent the evolution of gas during solidification 
 
4 Conditions of manufacture 
 
4.1 Steelmaking 
 
Unless otherwise agreed by the interested parties, the processes used in making the steel and in 
manufacturing hot-rolled sheet are left to the discretion of the manufacturer. On request, the purchaser shall be informed of the steelmaking process being used.  
4.2 Chemical composition 
 
The chemical composition (heat analysis) shall conform to the requirements given in Table 1. 
 
4.3 Chemical analysis 
 
4.3.1 Heat analysis  
An analysis of each heat of steel shall be made by  the manufacturer in order to determine compliance 
with the requirements given in Table 1. When requested, at the time of ordering, this analysis shall be 
reported to the purchaser or to his representative. 
 
4.3.2 Product analysis  
A product analysis may be made by the purchaser in order to verify the specified analysis of the 
product and shall take into consideration any normal  heterogeneity. Non-killed steels (such as rimmed 
or capped) are not technologically suited to product analysis. For aluminum killed steels, the sampling method and deviation limits shall be agreed upon between the interested parties at the time of 
ordering.

NOTE 1 Nitrogen content is controlled; normally it should not exceed 0.009 % for NE steel or 0.015 % for CS steel. 
 
NOTE 2 Each grade includes at least one microalloying element such as vanadium, titanium, niobium, etc.  
a Class C steels are to be used in cases where, owing to conditions and the general design of the structure, some 
resistance to brittle fracture is necessary. Class D steels are to be used in cases where,owing to loading conditions and the 
general design of the structure, a high resistance to brittle fracture is necessary.  
b NE = non-rimming; CS = aluminum killed. 
 
4.4 Weldability 
 
The product is suitable for welding if appropriate welding conditions are selected. For undescaled 
steel it may be necessary to remove the scale or oxide depending upon the welding method. As the carbon content increases above 0.15 %, spot welding becomes increasingly difficult.  
4.5 Application 
 
It is desirable that the specified product be identified for fabrication by the name of the part or by the 
intended application, which shall be compatible with the grade and class specified. Proper identification of the part may include visual examination, prints or description, or a combination of 
these. 
 
4.6 Mechanical properties 
 
At the time that the steel is made available for shipment, the mechanical properties shall be as stated in Table 2, if they are determined on test pieces obtained in accordance with the requirements of 
clause 7. 
 
4.7 Surface condition 
 
Oxide or scale on hot-rolled steel sheet is subject to variations in thickness, adherence and colour. 
Removal of the oxide or scale by pickling or blas t cleaning may disclose surface imperfections not 
readily visible prior to this operation. 
 
4.8 Oiling 
 As a deterrent to rusting, a coating of oil is usually applied to hot-rolled descaled steel sheet but sheet 
may be furnished not oiled, if required. The oil is not intended as a drawing or forming lubricant and should be easily removable with degreasing chemicals. On request, the manufacturer shall advise the 
purchaser which type of oil has been used. Hot rolled descaled steel sheet may be ordered unoiled, if 
required, in which case, the supplier has lim ited responsibility if oxidation occurs.

6 Tensile test sampling 
 
One representative sample for the tensile test required in Table 2 shall be taken from each lot of material for shipment. A lot consists of 50 tonnes or less of material of the same designation to the 
same thickness and condition. 
 
7 Tensile test 
 
The tensile test shall be carried out in accordance with ISO 6892. Transverse test pieces shall be taken midway between the centre and edge of the sheet as rolled.

8.1 Machining and flaws 
 
If any test piece shows defective machining or develops flaws, it shall be discarded and another test piece substituted. 
 
8.2 Elongation 
 
If the percentage elongation of any test piece is less th an that specified in Table 2 and if any part of 
the fracture is outside the middle half of the gauge length as scribed before the test, the test shall be 
discarded and a retest shall be carried out. 
 
8.3 Additional tests 
 
If a test does not give the specified results, two more tests shall be carried out at random on the same 
lot. Both retests shall conform to the requirements  of this International Standard; otherwise the lot 
may be rejected.  
9 Resubmission 
 
The manufacturer may resubmit for acceptance the products that have been rejected during earlier 
inspection because of unsatisfactory properties, after he has subjected them to a suitable treatment 
(selection, heat treatment), wh ich, on request, will be indicated to the purchaser. 
 
In this case, the tests should be carried out as if they applied to a new batch. 
 The manufacturer has the right to present the rejected products to a new examination for compliance 
with the requirements for another grade or class. 
 
10 Workmanship 
 The surface condition shall be that normally obtained in a hot-rolled or hot-rolled and descaled product. 
 
The steel sheet in cut lengths shall be free from any lamination, surface flaw s and other imperfections 
that are detrimental to the final product or to subsequent appropriate processing. 
 
Processing for shipment in coils does not afford the manufacturer the opportunity of readily observing or removing imperfect portions as can be carried out on the cut length product. 
 
11 Inspection and acceptance 
 11.1 While not usually required for products covered by this International Standard, when the 
purchaser specifies that inspection and tests for acceptance be observed prior to shipment from the 
manufacturer's works, the manufacturer shall afford the purchaser's inspector all reasonable facilities to determine that the steel is being furnished in accordance with this International Standard. 
 
11.2 Steel that is reported to be defective after arrival at the user's works shall be set aside, 
properly and correctly identified and adequately protec ted. The manufacturer shall be notified in order 
that he may properly investigate. 
 
12 Coil Size 
 
When hot-rolled steel sheet is ordered in coils, a minimum inside diameter (ID) or range of acceptable inside diameters shall be specified. In addition, the maximum outside diameter (OD) and the
