Designation:A 682/A 682M 05Standard Specification forSteel,Strip,High-Carbon,Cold-Rolled,GeneralRequirements For1This standard is issued under the fixed designationA 682/A 682M;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(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope*1.1 This specification covers the general requirements forcold-rolled carbon spring steel strip in coils or cut lengths.Strip is classified as product that is 0.3000 in.(7.6 mm)or lessin thickness and over12to 231516in.(12.5 to 600 mm)inwidth,inclusive.Strip tolerance products may be available inwidths wider than 231516in.(600 mm)by agreement betweenpurchaser and supplier;however,such products are technicallyclassified as cold-rolled sheet.1.2 The maximum of the specified carbon range is over0.25%to 1.35%,inclusive.1.3 The above shall apply to the cold-rolled carbon springsteel strip furnished under each of the following specificationsissued by ASTM:Title of SpecificationASTMDesignationSteel,Strip,High Carbon,Cold RolledA 684/A 684M1.4 The tolerances in this specification are different thanthose in Specification A 568/A 568M and Specification A 109/A 109M.1.5 For the purpose of determining conformance with thisspecification,values shall be rounded to the nearest unit in theright hand place of figures used in expressing the limitingvalues in accordance with the rounding method of PracticeE 29.1.6 The metric portions of the tables herein list permissiblevariations in dimensions and mass(see Note 1)in SI(metric)units.The values listed are not exact conversions of the valueslisted in the inch-pound tables but instead are rounded orrationalized values.Conformance to SI tolerances is mandatorywhen the“M”specification is used.NOTE1The term weight is used when inch-pound units are thestandard.However,under SI the preferred term in mass.1.7 The values stated in either inch-pound units or SI unitsare to be regarded as standard.Within the text,the SI units areshown in brackets.The values stated in each system are notexact equivalents;therefore,each system must be used inde-pendently of the other.Combining values from the two systemswill result in nonconformance with the specification.1.8 This specification is expressed in both inch-pound unitsand SI units.However,unless the order specifies the applicable“M”specification designation(SI units),the material shall befurnished to inch-pound units.2.Referenced Documents2.1 ASTM Standards:2A 109/A 109M Specification for Steel,Strip,Carbon(0.25Maximum Percent),Cold-RolledA 370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA 568/A 568M Specification for Steel,Sheet,Carbon,andHigh-Strength,Low-Alloy,Hot-Rolled and Cold-Rolled,General Requirements forA 684/A 684M Specification for Steel,Strip,High-Carbon,Cold-RolledA 700 Practices for Packaging,Marking,and LoadingMethods for Steel Products for Domestic ShipmentA 751 Test Methods,Practices,and Terminology forChemical Analysis of Steel ProductsA 941 Terminology Relating to Steel,Stainless Steel,Re-lated Alloys,and FerroalloysE 29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE 527 Practice for Numbering Metals and Alloys(UNS)2.2Federal Standards:3Fed.Std.No.123 Marking for Shipments(Civil Agencies)Fed.Std.No.183Continuous Identification Marking ofIron and Steel Products2.3Military Standards:3MIL-STD-129 Marking for Shipping and Storage1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel,and RelatedAlloys,and is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved Dec.1,2005.Published December 2005.Originallyapproved in 1973.Last previous edition approved in 2002 as A 682/A 682M 02.2For 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 Standardization Documents Order Desk,DODSSP,Bldg.4,Section D,700 Robbins Ave.,Philadelphia,PA 19111-5098.1*A Summary of Changes section appears at the end of this standard.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.MIL-STD-163 Steel Mill Products Preparation for Ship-ment and Storage2.4SAE Standard:4J 1086 Recommended Practice for Numbering Metals andAlloys(UNS)3.Terminology3.1 Definitions:3.1.1 burrmetal displaced beyond the plane of the surfaceby slitting or shearing.3.1.2 decarburizationrefer to Terminology A 941.3.1.3 lotquantity of material of the same type,size,andfinish produced at one time from the same cast or heat,and heattreated in
