1、Designation:A705/A705M13Standard Specification forAge-Hardening Stainless Steel Forgings1This standard is issued under the fixed designation A705/A705M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A numbe
2、r in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification2covers age-hardening stainless steelforgings for general use.1.2 The values stated in either SI units or inch-pound unitsare
3、 to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 Unless the order specifies an“M”designation,themat
4、erial shall be furnished to inch-pound units.NOTE1Bar products are covered by Specification A564/A564M.2.Referenced Documents2.1 ASTM Standards:3A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA484/A484M Specification for General Requirements forStainless Steel Bars,Billets,

10、f Specification A484/A484M,constitutes non-conformance with this specification.5.Materials and Manufacture5.1 Material for forgings shall consist of billets or bars,either forged,rolled or cast,or a section cut from an ingot.Thecuts shall be made to the required length by a suitable process.This mat
11、erial may be specified to Specification A564/A564M.5.2 The material shall be forged by hammering,pressing,rolling,extruding,or upsetting to produce a wrought structurethroughout and shall be brought as nearly as possible to thefinished shape and size by hot working.5.3 When specified on the order,sa
12、mple forging may besectioned and etched to show flow lines and the condition inregard to internal imperfections.When so specified,the ques-tion of acceptable and unacceptable metal flow shall be subjectto agreement between the manufacturer and the purchaser priorto order entry.1This specification is
