Abstract
This specification covers hot-rolled and cold-rolled alloy steel sheet and strip. The steel materials shall be melt processed, hot rolled, cold rolled, and heat treated. Cast or heat analysis and product analysis shall be performed wherein the specimens shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, vanadium, tungsten, and aluminum. The steel materials shall conform to the required metallurgical structure and yield strength. The types of edges procurable in the steel materials are as follows: (1) mill edge; (2) cut edge; (3) square edge; and (4) rounded edge.
Scope
1.1 This specification covers a group of common requirements that, unless otherwise specified in the material specification, apply to hot-rolled and cold-rolled alloy steel sheet and strip under each of the following specifications: A506, A507, and A873/A873M.
1.2 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.
1.3 The purchaser may specify additional requirements which do not negate any of the provisions of this general specification or of the individual material specification. Such additional requirements, the acceptance of which are subject to negotiation with the supplier, must be included in the order information (see 4.1.9).
1.4 For purposes of determining conformance with this specification and the various material specifications referenced in 1.1, values shall be rounded to the nearest unit in the right-hand place of figures used in expressing the limiting values in accordance with the rounding provisions of Test Methods and Definitions A370 and Test Methods, Practices, and Terminology A751.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 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.
