(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:

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.

1.8The values stated in either inch-pound units and SI units (metric) are to be regarded separately as standard. Within the text
the SI units are shown in brackets.The values stated in each system are not exact equivalents; therefore, each system must be used

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
