16、pecification, all requirements of the current edition of Specification A484/A484Mshall apply. Failure to comply with the general requirements of Specification A484/A484M, constitutes nonconformance with thisspecification.5. Materials and Manufacture5.1 Material for forgings shall consist of billets
17、or bars, either forged, rolled or cast, or a section cut from an ingot. The cutsshall be made to the required length by a suitable process. This material may be specified to Specification A564/A564M.5.2 The material shall be forged by hammering, pressing, rolling, extruding, or upsetting to produce
18、a wrought structurethroughout and shall be brought as nearly as possible to the finished shape and size by hot working.5.3 When specified on the order, sample forging may be sectioned and etched to show flow lines and the condition in regardto internal imperfections. When so specified, the question
19、of acceptable and unacceptable metal flow shall be subject to agreementbetween the manufacturer and the purchaser prior to order entry.5.4 When specified on the order, the manufacturer shall submit for approval of the purchaser a sketch showing the shape of therough forging before machining, or befo
20、re heat treating for mechanical properties.5.5 The grain size shall be as fine as practicable and precautions shall be taken to minimize grain growth.5.6 Material of types other than XM-9 shall be furnished in the solution-annealed condition, or in the equalized andover-tempered condition, as noted
21、in Table 2, unless otherwise specified by the purchaser.5.6.1 Types 630, XM-16, and XM-25 may be furnished in the solution-annealed or age-hardened condition.6. Chemical Composition6.1 The steel shall conform to the chemical composition limits specified in Table 1.6.2 Methods and practices relating
22、to chemical analysis required by this specification shall be in accordance with Test Methods,Practices, and Terminology A751.7. Mechanical Properties7.1 The material, as represented by mechanical test specimens, shall conform to the mechanical property requirements specifiedin Table 2 and shall be c
23、apable of developing the properties in Table 3 when heat treated as specified in Table 3.7.2 The yield strength shall be determined by the offset method as described in the current edition of Test Methods andDefinitions A370. The limiting permanent offset shall be 0.2 % of the gage length of the spe
24、cimen.7.3 The impact strength shall be determined at 70 to 80F 20 to 25C, by Charpy V-notch specimen Type A as described inTest Methods and Definitions A370.TABLE 1 Chemical RequirementsAComposition, %UNSDesignationBType Carbon Manganese Phospho-rusSul-furSili-conChromium Nickel Alumi-numMolyb-denum
