This specification covers hot-rolled, heavy thickness coils beyond the size limits of Specifications A506 and A507.

The product is available in three designations: Alloy Steel, Drawing Steel, and Structural Alloy Steel.

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.

Drawing steel is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts.

Drawing steel may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein.

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.

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.

This material is available only in coils described as follows:

Sheet and strip in coils of sizes noted in 1.6 are covered by this specification only with the following provisions:

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.

The dimensional tolerances of Specification A635/ A635M are applicable to material produced to this specification.

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.

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.

Within the text the SI units are shown in brackets.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
