Designation: A 480/A 480M – 08a

Standard Specification for

General Requirements for Flat-Rolled Stainless and HeatResisting Steel Plate, Sheet, and Strip1
This standard is issued under the fixed designation A 480/A 480M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicatesthe year of last reapproval. A superscript epsilon (´) 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 specification2 covers a group of general requirements that, unless otherwise specified in the purchase order or in an individual specification, shall apply to rolled steelplate, sheet, and strip, under each of the following specifications issued by ASTM: Specifications A 167, A 176, A 240/A 240M, A 263, A 264, A 265, A 666, A 693, A 793, and A 895. 1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the productspecification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent. 1.3 The values stated ineither inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets, except that when A 480M is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combiningvalues from the two systems may result in nonconformance with the specification. 1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished in inch-pound units.

1 This specification is under the jurisdiction of ASTM CommitteeA01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.17 on Flat-Rolled and Wrought Stainless Steel. Current edition approved May 15, 2008. Published June 2008. Originally approved in 1962. Last previous edition approved in 2008 as A 480/A 480M – 08. 2 For ASME Boiler and Pressure Vessel Code applications see related Specification SA – 480 in Section IIof that Code.
