1、Designation: A 506 05Standard Specification forAlloy and Structural Alloy Steel, Sheet and Strip, Hot-Rolledand Cold-Rolled1This standard is issued under the fixed designation A 506; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification cove

3、rs hot-rolled and cold-rolledalloy and structural alloy-steel sheet and strip. Alloy steel isfurnished to chemical composition requirements and is in-tended primarily for general or miscellaneous use wherebending and moderate forming is a requirement. Structuralalloy steel is furnished to chemical c

4、omposition requirementsand to specific mechanical property requirements which mayinclude tension tests, hardness tests, or other commonlyaccepted mechanical tests.1.2 If material of a higher degree of uniformity of internalsoundness and freedom from surface imperfections is required,reference should

5、 be made to Specification A 507.1.3 Alloy and structural alloy-steel sheet and strip are notproduced to internal cleanliness requirements. Normally sur-face imperfections are not objectionable, and a good finish isnot a prime requirement.1.4 The formability of structural alloy steel decreases within

6、creasing yield strength or hardness. Therefore, product de-sign in relation to the mechanical properties of the grade usedmust be considered.1.5 The material covered by this specification may befurnished in several conditions: heat treatments, surface con-ditions, and edges, as specified herein, in

7、coils or cut lengths.1.6 The values stated in inch-pound units are to be regardedas the standard. SI units are provided for information only.2.
