(Specification)Standard Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Alloy, Drawing Steel and Structural Steel, Hot-Rolled
Standard Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Alloy, Drawing Steel and Structural Steel, Hot-Rolled
ABSTRACT
This specification deals with the hot-rolled, heavy thickness coils available for three designations: alloy steel, drawing steel, and structural alloy steel. Alloy steel is intended for general or miscellaneous use where bending and moderate forming is required. Drawing steel is used for severe cold plastic deformation such as deep drawn or severely formed parts. The material is available only in coils such as strip and sheet. As-rolled and annealed heat treatment shall be used for manufacturing the material. Drawing steel shall be furnished with a spheroidized annealed heat treatment unless otherwise specified. Heat analysis shall conform to the required grade specified for standard alloy steel, nonstandard alloy steel, and structural alloy steel. Grades shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Mechanical tests for regular quality alloy steel and strip are not applicable; but for drawing steel and structural alloy steel, tension and hardness tests are required.
SCOPE
1.1 This specification covers hot-rolled, heavy thickness coils beyond the size limits of Specifications A506 and A507.
1.2 The product is available in three designations: Alloy Steel, Drawing Steel, and Structural Alloy Steel.
1.3 Alloy steel is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement.
1.4 Drawing steel is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts.
1.4.1 Drawing steel may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein.
1.5 Structural steel is furnished to chemical composition requirements and to specific mechanical property requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.
1.5.1 The formability of structural steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.
1.6 This material is available only in coils described as follows: ProductSize Limits, Coils Only Width, in. [mm]Thickness, in. [mm] StripOver 8 to 12, incl0.230 to 1.000, incl [Over 200 to 300][Over 6.0 to 25] SheetOver 120.230 to 1.000, incl [Over 300][from 6.0 through 25]
1.7 Sheet and strip in coils of sizes noted in 1.6 are covered by this specification only with the following provisions:
1.7.1 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A6/A6M (plates provided from coils) or A20/A20M (plates produced from coils). A plate produced in this manner is no longer governed by this sheet steel specification and since this material is now plate, the appropriate plate standard must now apply.
1.7.2 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.
1.7.3 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.
1.8 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.8.1 Within the text the SI units are shown in brackets.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
