Designation:A705/A705M17Standard 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 number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification2covers age-hardening stainless steelforgings for general use.1.2 The values stated in either SI units or inch-pound unitsare 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,thematerial shall be furnished to inch-pound units.NOTE1Bar products are covered by Specification A564/A564M.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.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,and ForgingsA564/A564M Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and ShapesA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsE527 Practice for Numbering Metals and Alloys in theUnified Numbering System(UNS)2.2 Other Documents:4SAE J 1086 Recommended Practice for Numbering Metalsand Alloys(UNS)3.Ordering Information3.1 It is the responsibility of the purchaser to specify allrequirements that are necessary for material ordered under thisspecification.Such requirements may include but are notlimited to the following:3.1.1 Quantity(weight or number of pieces),3.1.2 Name of material(age-hardening stainless steelforgings),3.1.3 Dimensions,including prints or sketches,3.1.4 Type or UNS designation(Table 1),3.1.5 Heat-treated condition(Section 5),3.1.6 Transverse properties when required(7.4),3.1.7 ASTM designation and date of issue,and3.1.8 Special requirements(5.3,5.4).3.2 If possible,the intended end use of the item should begiven on the purchase order,especially when the item isordered for a specific end use or uses.NOTE2A typical ordering description is as follows:5 age-hardeningstainless steel forgings,Type 630,solution-annealed,ASTM SpecificationA705 dated _.End use:pump blocks for oil well equipment.4.General Requirements4.1 In addition to the requirements of this specification,allrequirements of the current edition of Specification A484/A484M shall apply.Failure to comply with the generalrequirements of 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 material 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 structure1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.17 on Flat-Rolled and Wrought Stainless Steel.Current edition approved Nov.15,2017.Published November 2017.Originallyapproved in 1974.Last previous edition approved in 2013 as A705/A705M 13.DOI:10.1520/A0705_A0705M-17.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-705/SA-705M in Section II of that Code.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.4Available from Society of Automotive Engineers(SAE),400 CommonwealthDr.,Warrendale,PA 15096-0001.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 throughout and shall be brought as nearly as possible to thefinished shape and size by hot working.5.3 When specified on the order,sample forging may besectioned and etched to show flow
