5、argrades 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 A336/A336M and A965/A965Mfor the similar ferritic and austenitic grades, respectively,
6、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. Several of the ferritic/austenitic(duplex) grades
7、are also found in Specification A1049/A1049M.1.4 Supplementary requirements are provided 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 unit
8、s. However, unless the order specifies theapplicable “M” specification designation (SI units), the mate-rial shall be furnished to inch-pound units.1.6 The values stated in either SI units or inch-pound unitsare to be regarded separately as the standard. Within the text,the SI units are shown in bra
9、ckets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard.2. Referenced Documents2.1 In addition to the referenced documents listed in Speci-
