This specification covers hot-rolled, heavy thickness coils beyond the size limits of Specifications A 506 and A 507.

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.

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 A 6/A 6M (plates provided from coils) or A 20/A 20M (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 A 635/A 635M 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 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 independently of each other.
