Designation:A313/A313M13Standard Specification forStainless Steel Spring Wire1This standard is issued under the fixed designation A313/A313M;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers austenitic,austenitic-ferritic,and age-hardenable stainless steel round spring wire intendedespecially for the manufacture of springs.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.2.Referenced Documents2.1 ASTM Standards:2A555/A555M Specification for General Requirements forStainless Steel Wire and Wire RodsA751 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 Society of Automotive Engineers Standard:3J 1086 Numbering Metals and Alloys3.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),3.1.2 Name of material(stainless steel spring wire),3.1.3 Finish(see 8.1),3.1.4 Dimension(diameter),3.1.5 Type designation(Table 1),3.1.6 ASTM designation and date of issue,3.1.7 Tensile strength level,when applicable(Table 11 andTable 12),3.1.8 Supplementaryrequirementsforgovernmentprocurement,and3.1.9 Special requirements.NOTE1A typical ordering description is as follows:2000 lb(1000 kg)Stainless Steel Spring Wire,cold-drawn Class 1,bright finish,0.032-in.(0.82 mm)diameter,in 100-lb(50 kg)16-in.(0.4m)coils,Type 302 to ASTM A313,dated _.4.General Requirements for Delivery4.1 In addition to the requirements of this specification,allrequirements of the current edition of Specification A555/A555M shall apply.Failure to comply with the generalrequirements of Specification A555/A555M constitutes non-conformance with this specification.5.Manufacture5.1 Types 302 Class 1,304,305,316,321,347,UNSS20230,and Grades S20430 and XM-28 shall be cold drawn toproduce the required mechanical properties.5.2 Type 631,Type 302 Class 2,and Grade XM-16 shall befurnished in the cold-drawn condition ready for fabrication.Following fabrication Type 631 and Grade XM-16 shall be ageor precipitation hardened to produce their maximum strengthproperties.The tensile strengths to be obtained following theprescribed heat treatment are shown in Table 2 and Table 3 forhardened wire.Type 302 Class 2 shall be stress relievedfollowing fabrication and meet the requirements shown inTable 4.The nominal as-drawn tensile strengths are providedas a guide for the spring manufacturer.5.3 Grade S30151 shall be either cold drawn or cold drawnand heat treated to produce the required mechanical properties.6.Chemical Composition6.1 The steel shall conform to the requirements as tochemical composition prescribed in Table 1.1This 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 Oct.1,2013.Published October 2013.Originallyapproved in 1947.Last previous edition approved in 2010 as A313/A313M 101.DOI:10.1520/A0313_A0313M-13.2For 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.3Available from Society of Automotive Engineers(SAE),400 CommonwealthDr.,Warrendale,PA 15096-0001,http:/www.sae.org.*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 States1Copyright by ASTM Intl(all rights reserved);6.2 Methods and practices relating to chemical analysisrequired by this specification shall be in accordance with TestMethods,Practices,and Terminology A751.7.Mechanical Requirements7.1 Tensile Properties:7.1.1 Types 302 Class 1 and 304 shall conform to therequirements shown in Table 5.7.1.2 Types 305,316,321,and 347 shall conform to therequirements shown in Table 6.7.1.3 Type 631 shall conform to the requirements shown inTable 2 when heat treated 900F 482C for 1 h and air cooled.TABLE 1 Chemical RequirementsUNSDesignati
