3、rial 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 specification2covers forged low alloy and stainlesssteel piping components for use in pressure systems. Includedare flanges, fittings, valves, and simi
4、lar parts to specifieddimensions or to dimensional standards, such as the ASMEspecifications that are referenced in Section 2.1.2 For bars and products machined directly from bar (otherthan those directly addressed by this specification; see 5.4),refer to SpecificationsA 479/A 479M andA 739 for the
5、similargrades available in those specifications. Products made to thisspecification are limited to a maximum weight of 10 000 lb4540 kg. For larger products and products for other applica-tions, refer to Specifications A 336/A 336M and A 965/A 965M for the similar ferritic and austenitic grades, res
6、pec-tively, available in those specifications.1.3 Several grades of low alloy steels and ferritic, marten-sitic, austenitic, and ferritic-austenitic stainless steels are in-cluded in this specification. Selection will depend upon designand service requirements.1.4 Supplementary requirements are prov
7、ided for use whenadditional testing or inspection is desired. These shall applyonly when specified individually by the purchaser in the order.1.5 This specification is expressed in both inch-pound unitsand in SI units. However, unless the order specifies theapplicable “M” specification designation (
8、SI units), the mate-rial shall be furnished to inch-pound units.1.6 The values stated in either inch-pound units or SI unitsare to be regarded separately as the standard. Within the text,the SI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each sy
9、stem mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.2.

Ordering Information3.1 It is the purchasers responsibility to
19、 specify in thepurchase order information necessary to purchase the neededmaterial. In addition to the ordering information guidelines inSpecificationA 961/A 961M, orders should include the follow-ing information:3.1.1 Additional requirements (see 6.2.1, Table 2 footnotes,8.3, and 17.2), and3.1.2 Re
20、quirement, if any, that manufacturer shall submitdrawings for approval showing the shape of the rough forgingbefore machining and the exact location of test specimenmaterial (see 8.3.1).4. General Requirements4.1 Product furnished to this specification shall conform tothe requirements of Specificati
21、on A 961/A 961M, includingany supplementary requirements that are indicated in thepurchase order. Failure to comply with the general require-ments of Specification A 961/A 961M constitutes nonconfor-mance with this specification. In case of conflict between therequirements of this specification and
22、Specification A 961/A 961M, this specification shall prevail.5. Manufacture5.1 The low-alloy ferritic steels shall be made by theopen-hearth, electric-furnace, or basic-oxygen process with theoption of separate degassing and refining processes in eachcase.5.2 The stainless steels shall be melted by
23、one of thefollowing processes: (a) electric-furnace (with the option ofseparate degassing and refining processes); (b) vacuum-furnace; or (c) one of the former followed by vacuum orelectroslag-consumable remelting. Grade F XM-27Cb may beproduced by electron-beam melting.5.3 A sufficient discard shal
