Hot-finished or cold-finishedrounds, squares, hexagons, bar shapes, angles, tees, andchannels are included; these shapes may be produced byhot rolling, extruding, or forging. Billets or bars for reforg ing may be purchased to this specification.A 314 Specification for Stainless Steel Billets and Bars forForgingA 370 Test Methods and Definitions for Mechanical Test ing of Steel ProductsA 484/A 484M Specification for General Requirementsfor Stainless Steel Bars, Billets, and ForgingsA 705/A 705M Specification for Age-Hardening, StainlessSteel ForgingsA 751 Test Methods, Practices, a n d Terminology forChemical Analysis of Steel ProductsE 527 Practice for Numbering Metals and Alloys (UNS)1.2 These steels are generally used for parts requiringcorrosion resistance and high strength at room temperature,or at temperatures up to 600 F [315 Cj; 700 F [370 C] forType 632. They are suitable for machining in the solution annealed condition after which they may be age-hardenedto the mechanical properties specified in Section 7 withoutdanger of cracking or distortion. Type XM-25 is machin able in the as-received fully heat treated condition.2.2 Other Documents:SAE J1086 Recommended Practice for Numbering Metalsand Alloys (UNS)1.3 Types 631 and 632 contain a large amount of ferritein the microstructure and can have low ductility in forgingsand larger diameter bars.

Such requirements may includebut are not limited to the following:1.4 The values stated in either inch-pound units or Sl(met ric) units arc to be regarded separately as standards;within the text and tables, the Sl units arc shown in [brack ets!. The values stated in each system are not exact equiva lents; th ; refore, each system rnust be used independent ofthe other.

The limiting permanent offset shallbe 0.2% of the gage length of the specimen.4.1 In addition to the requirements of this specification,all requirements of the current edition of SpecificationsA 484/A 484M shall apply. Failure to comply with thegeneral requirements of Specification A 484/A 484M con stitutes nonconformance with this specification.5.7.7.2 Samples cut from bars for forging stock shall con form to the mechanical properties of Table 2 and Table 3when heat treated as specified in Table 2 and Table 3.
