(Specification)Standard Specification for Alloy and Structural Alloy Steel, Sheet and Strip, Hot-Rolled and Cold-Rolled
Standard Specification for Alloy and Structural Alloy Steel, Sheet and Strip, Hot-Rolled and Cold-Rolled
ABSTRACT
This specification covers the standard for hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. The material shall be furnished in several conditions: heat treatments such as hot-rolling and cold rolling; surface conditions; and edges, as specified herein, in coils or cut lengths. Heat analysis shall be performed on the material and shall conform to the required chemical compositions for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Materials in the annealed, normalized, or normalized-and-tempered condition shall be capable of meeting the longitudinal bend test requirements. Two tension tests and two hardness tests shall be made from coupons obtained from each heat (cast) and heat treatment lot.
SCOPE
1.1 This specification covers hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. 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. Structural alloy 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.
1.2 If material of a higher degree of uniformity of internal soundness and freedom from surface imperfections is required, reference should be made to Specification A 507.
1.3 Alloy and structural alloy-steel sheet and strip are not produced to internal cleanliness requirements. Normally surface imperfections are not objectionable, and a good finish is not a prime requirement.
1.4 The formability of structural alloy steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.
1.5 The material covered by this specification may be furnished in several conditions: heat treatments, surface conditions, and edges, as specified herein, in coils or cut lengths.
1.6 The values stated in inch-pound units are to be regarded as the standard. SI units are provided for information only.
