ASTM A506-00

Standard Specification for Alloy and Structural Alloy Steel, Sheet and Strip, Hot-Rolled and Cold-Rolled

SCOPE
1.1 This specification covers hot-rolled and cold-rolled regular quality and structural quality alloy-steel sheet and strip. Regular quality is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement. Structural quality 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 A507.  
1.3 Regular quality and structural quality 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 quality 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.
