Designation:A635/A635M15Standard Specification forSteel,Sheet and Strip,Heavy-Thickness Coils,Hot-Rolled,Alloy,Carbon,Structural,High-Strength Low-Alloy,andHigh-Strength Low-Alloy with Improved Formability,GeneralRequirements for1This standard is issued under the fixed designation A635/A635M;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 the general requirements forhot-rolled,heavy-thickness sheet and strip in coils.1.2 It applies to Specifications A414/A414M,A424/A424M,and A1018/A1018M.1.3 This material is available only in coils described asfollows:Size Limits,Coils OnlyProductWidth,in.mmThickness,in.mmStripover 8 to 12,inclover 200 through 3000.230 to 1.000,inclfrom 6.0 through 25SheetAll WidthsAAll Widths0.230 to 1.000,inclfrom 6.0 through 25AHot-rolled heavy thickness sheet in coils less than 12 in.300 mm and less inwidth must have slit edges.Hot-rolled heavy thickness coils 12 in.300 mm andwider with mill edge is considered hot-rolled heavy thickness strip.NOTE1The changes in width limits with the publication of A635/A635M 06a result in a change in tensile testing direction for materialfrom 0.180 in.4.5 mm to 0.230 in.exclusive 6.0 mm exclusive over 48in.1200 mm wide,as that material is now covered by SpecificationA568/A568M 06a.The purchaser is advised to discuss this change withthe supplier.1.4 In case of any conflict in requirements,the requirementsof the individual material specification shall prevail over thoseof this general specification.1.5 AnnexA1 lists permissible variations in dimensions andmass(see Note 2)in SI metric units.The values listed are notexact conversions of the values listed in the inch-pound tables,but instead are rounded or rationalized values.Conformance toAnnex A1 is mandatory when the“M”specification is used.NOTE2The term weight is used when inch-pound units are thestandard.However,under SI,the preferred term is mass.1.6 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.1.7 This specification and the applicable material specifica-tions are expressed in both inch-pound units and SI units.However,unless the order specifies the applicable“M”speci-fication designation(SI units),the material shall be furnishedto inch-pound units.2.Referenced Documents2.1 ASTM Standards:2A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA414/A414M Specification for Steel,Sheet,Carbon,andHigh-Strength,Low-Alloy for Pressure VesselsA424/A424M Specification for Steel,Sheet,for PorcelainEnamelingA568/A568M Specification for Steel,Sheet,Carbon,Structural,and High-Strength,Low-Alloy,Hot-Rolled andCold-Rolled,General Requirements forA700 Guide for Packaging,Marking,and Loading Methodsfor Steel Products for ShipmentA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and FerroalloysA1018/A1018M Specification for Steel,Sheet and Strip,Heavy-ThicknessCoils,Hot-Rolled,Carbon,1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved Nov.1,2015.Published November 2015.Originallyapproved in 1970.Last previous edition approved in 2014 as A635/A635M 14.DOI:10.1520/A0635_A0635M-15.2For 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.*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 States1 Commercial,Drawing,Structural,High-Strength Low-Alloy,High-StrengthLow-AlloywithImprovedFormability,and Ultra-High StrengthA1073/A1073M Practice for Using Hand Micrometers toMeasure the Thickness of Nonmetallic and Metallic-Coated Steel SheetE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications2.2 Federal Standards:3Fed.Std.No.123 Marking for Shipment(Civil Agencies)2.3 Military Standards:3MIL-STD-129 Marking for Shipment and Storage3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 Steel Types:3.1.2 carbon steel,nthe desig
