Designation:A1031/A1031M12Standard Specification forSteel,Sheet and Strip,Heavy-Thickness Coils,Alloy,Drawing Steel and Structural Steel,Hot-Rolled1This standard is issued under the fixed designation A1031/A1031M;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 hot-rolled,heavy thicknesscoils beyond the size limits of Specifications A506 and A507.1.2 The product is available in three designations:AlloySteel,Drawing Steel,and Structural Alloy Steel.1.3 Alloy steel is furnished to chemical composition re-quirements and is intended primarily for general or miscella-neous use where bending and moderate forming is a require-ment.1.4 Drawing steel is produced principally for applicationsinvolving severe cold plastic deformation such as deep drawnor severely formed parts.1.4.1 Drawing steel may be furnished in several conditions,heat treatments,surface finishes,and edges,as specified herein.1.5 Structural steel is furnished to chemical compositionrequirements and to specific mechanical property requirementswhich may include tension tests,hardness tests,or othercommonly accepted mechanical tests.1.5.1 The formability of structural steel decreases withincreasing yield strength or hardness.Therefore,product de-sign in relation to the mechanical properties of the grade usedmust be considered.1.6 This material is available only in coils described asfollows:ProductSize Limits,Coils OnlyWidth,in.mmThickness,in.mmStripOver 8 to 12,incl0.230 to 1.000,inclOver 200 to 300Over 6.0 to 25SheetOver 120.230 to 1.000,inclOver 300from 6.0 through 251.7 Sheet and strip in coils of sizes noted in 1.6 are coveredby this specification only with the following provisions:1.7.1 The material is not to be converted into steel plates forstructural or pressure vessel use unless tested in completeaccordance with the appropriate sections of SpecificationsA6/A6M(plates provided from coils)or A20/A20M(platesproduced from coils).A plate produced in this manner is nolonger governed by this sheet steel specification and since thismaterial is now plate,the appropriate plate standard must nowapply.1.7.2 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specifica-tion.1.7.3 The material is to be fed directly from coils into ablanking press,drawing or forming operation,tube mill,rollingmill,or sheared or slit into blanks for subsequent drawing orforming.1.8 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.1.8.1 Within the text the SI units are shown in brackets.2.Referenced Documents2.1 ASTM Standards:2A6/A6M Specification for General Requirements for RolledStructural Steel Bars,Plates,Shapes,and Sheet PilingA20/A20M Specification for General Requirements for SteelPlates for Pressure VesselsA370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA505 Specification for Steel,Sheet and Strip,Alloy,Hot-Rolled and Cold-Rolled,General Requirements forA506 Specification for Alloy and Structural Alloy Steel,Sheet and Strip,Hot-Rolled and Cold-RolledA507 Specification for DrawingAlloy Steel,Sheet and Strip,Hot-Rolled and Cold-Rolled1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloysand is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved May 1,2012.Published May 2012.Originallyapproved in 2004.Last previous edition approved in 2010 as A1031/A1031M 10.DOI:10.1520/A1031_A1031M-12.2For 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 States1Copyright by ASTM Intl(all rights reserved);A635/A635M Specification for Steel,Sheet and Strip,Heavy-Thickness Coils,Hot-Rolled,Alloy,Carbon,Struc-tural,High-Strength Low-Alloy,and High-Strength Low-Alloy with Improved Formability,General RequirementsforE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications3.General Requirements for Delivery3.1 Material furnished under this specification shall con-form to the applicable requirements of Specification A505,current edition,unless otherwise provided herein.4.Ordering Information4.1 Orders for materia
