Designation:A794/A794M12Standard Specification forCommercial Steel(CS),Sheet,Carbon(0.16%Maximum to0.25%Maximum),Cold-Rolled1This standard is issued under the fixed designation A794/A794M;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 Department of Defense.1.Scope*1.1 This specification covers cold-rolled commercial steel(CS)sheet in coils and cut lengths,in which the maximum ofthe specified carbon range is over 0.15 and not over 0.25%,and the maximum of the specified manganese range is not over0.90%.This material is ordered to chemical composition.1.2 This specification is not applicable to the steels coveredin Specifications A109/A109M and A1008/A1008M.1.3 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:2A109/A109M Specification for Steel,Strip,Carbon(0.25Maximum Percent),Cold-RolledA568/A568M Specification for Steel,Sheet,Carbon,Struc-tural,and High-Strength,Low-Alloy,Hot-Rolled andCold-Rolled,General Requirements forA749/A749M Specification for Steel,Strip,Carbon andHigh-Strength,Low-Alloy,Hot-Rolled,General Require-ments forA1008/A1008M Specification for Steel,Sheet,Cold-Rolled,Carbon,Structural,High-Strength Low-Alloy,High-Strength Low-Alloy with Improved Formability,SolutionHardened,and Bake HardenableE527 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 purchasers responsibility to specify in thepurchase order all ordering information necessary to purchasethe needed material.Examples of such information,include butare not limited to,the following:3.1.1 ASTM specification number and year of issue,3.1.2 Name of material(cold-rolled commercial steel(CS)sheet),3.1.3 Grade designation or chemical composition or both,3.1.4 Copper-bearing steel(if required),3.1.5 Finish;indicate unexposed with matte(dull)finish,orexposed with either matte(dull),commercial bright or lusterfinish,as required,3.1.6 Specify oiled or not oiled,as required,3.1.7 Dimensions(thickness,width,and whether cut lengthsor coils),NOTE1Not all producers are capable of meeting all the limitations ofthe thickness tolerance tables in Specification A568/A568M.The pur-chaser should contact the producer regarding possible limitations prior toplacing an order.3.1.8 Coil size(must include inside diameter,outside diam-eter,and maximum mass),3.1.9 Quantity,3.1.10 Application(show part identification and descrip-tion),3.1.11 Cast or heat analysis report(request,if required),and3.1.12 Special requirements(if any).3.1.12.1 When the purchaser requires thickness tolerancesfor38in.10 mm minimum edge distance(see SupplementaryRequirement in Specification A568/A568M),this requirementshall be specified in the purchase order or contract.NOTE2Atypical ordering description is as follows:ASTMA794-XX,Cold-Rolled Commercial Steel(CS),Grade 1018,Exposed,Matte Finish,Oiled,0.030 by 36 by 96 in.,100 000 lb.,for Part No.5226 Steel1This 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 1982.Last previous edition approved in 2009 as A794 09.DOI:10.1520/A0794_A0794M-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.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);Shelving,or,ASTM A794M-XX,Cold-Rolled Commercial Steel(CS),Grade 1018,Exposed,Matte Finish,Oiled 0.75 by 915 by 2438 mm,45,000 kg,for Part N.5226 Steel Shelving.4.Manufacture4.1 ConditionThe material shall be furnished in the an-nealed and temper-rolled condition but may be supplied fullhard if specified.5.Chemical Composition5.1 The cast or heat(formerly ladle)analysis of the steelshall conform to the chemical requirements shown in Table 1,or chemical compositions can be specified from carbon 0.16%maximum t
