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.
