Designation:A1000/A1000M11Standard Specification forSteel Wire,Carbon and Alloy Specialty Spring Quality1This standard is issued under the fixed designation A1000/A1000M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers four different grades of roundand shaped plain carbon and alloy steel spring wire,uniform inquality and temper,intended for the manufacture of mechanicalsprings that can withstand moderate fatigue stresses over somerelatively low number of cycles.The quality level is betweenthe commercial quality grades of wire such as SpecificationsA401/A401M,A231/A231M,and A229/A229M and the valvespring quality grades such Specifications as A230/A230M,A232/A232M,and A877/A877M.It is similar to the grade TD(referenced in EN 10270-2)intended for medium fatiguelevels,such as required for clutch springs.This wire shall beeither in the annealed and cold-drawn or quenched andtempered condition as specified by purchaser.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.2.Referenced Documents2.1 ASTM Standards:2A229/A229M Specification for Steel Wire,Quenched andTempered for Mechanical SpringsA230/A230M Specification for Steel Wire,Oil-TemperedCarbon Valve Spring QualityA231/A231M Specification for Chromium-Vanadium AlloySteel Spring WireA232/A232M Specification for Chromium-Vanadium AlloySteel Valve Spring Quality WireA370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA401/A401M Specification for Steel Wire,Chromium-Silicon AlloyA700 Practices for Packaging,Marking,and Loading Meth-ods for Steel Products for ShipmentA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsA877/A877M Specification for Steel Wire,Chromium-Silicon Alloy,Chrome-Silicon-Vanadium Alloy ValveSpring QualityA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and FerroalloysE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE45 Test Methods for Determining the Inclusion Content ofSteel2.2 European Standard:EN 10270-2 Steel Wire for Mechanical Springs Part 2:Oil-Hardened and Tempered Springsteel Wire of Unal-loyed and Alloyed Steels33.Terminology3.1 Definitions:3.1.1 For definition of terms used in this specification,seeTerminology A941.3.2 Definitions of Terms Specific to This Standard:3.2.1 commercial quality wirea grade of wire that is fairlycommon quality and intended for applications that are primar-ily static in nature,not involving significant fatigue loading.4.Ordering Information4.1 It shall be the responsibility of the purchaser to specifyall requirements that are necessary for material under thisspecification.Such requirements are permitted to include,butare not limited to the following,4.1.1 Quantity(mass),4.1.2 Name of material(chromium-silicon alloy steel spe-cialty spring quality wire),4.1.3 Dimensions(Table 1 and Section 9),4.1.4 Condition(Section 7),4.1.5 Packaging(Section 15),4.1.6 Heat analysis report,if requested(6.2),1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloysand is the direct responsibility of SubcommitteeA01.03 on Steel Rod and Wire.Current edition approved July 1,2011.Published July 2011.Originally approvedin 1999.Last previous edition approved in 2005 as A1000 05.DOI:10.1520/A1000_A1000M-11.2For 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 European Committee for Standardization,rue de Stassart36,B-1050 Brussels*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);4.1.7 Certification or test report,or both,if specified(Sec-tion 14),and4.1.8 ASTM designation and year of issue.NOTE1A typical ordering description is as follows:40 000-lb.quenched and tempered chromium-silicon alloy steel specialty springquality wire,size 0.250 in.in 3000-lb coils to Specification A1000/A1000M dated _,or for SI units,20 000-kg quenched andtempered chromium-silicon alloy steel specialty spring quality wire,size6.00 mm in 1500-kg coils to Specification A1000/A1000M dated _.5.Materials and Manufacture5.1 The steel may be made by any commercially acceptedsteel making process.The ste
