Designation:A413/A413M07(Reapproved 2012)Standard Specification forCarbon Steel Chain1This standard is issued under the fixed designation A413/A413M;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 carbon steel chain for suchapplications as railroad cars,construction,industrial uses,loadbinding,and general purposes other than overhead lifting.NOTE1This specification does not cover carbon steel chain forsprocket applications.1.2 Three classes of carbon steel chain are covered:1.2.1 Grade 30Proof coil chain.1.2.2 Grade 43High test chain.1.2.3 Grade 70Transport chain.1.3 The Grade designation is110of the minimum breakingstrength in newtons divided by two times the nominal cross-sectional area of the chain in square millimetres.1.4 The values stated in either acceptable metric units or inother units shall be regarded separately as standard.The valuesstated in each system may not be exact equivalents;therefore,each system must be used independently of the other,withoutcombining values in any way.2.Referenced Documents2.1 ASTM Standards:2A29/A29M Specification for Steel Bars,Carbon and Alloy,Hot-Wrought,General Requirements forA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and Ferroalloys3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 breaking force,minimum,nminimum force inpounds or newtons at which the chain,during manufacture,hasbeen found by testing to break when a constantly increasingforce is applied in direct tension.3.1.1.1 DiscussionThis test is a manufacturers attributeacceptance test and shall not be used as criteria for service.3.1.2 lot,nfor the purpose of acceptance testing,a lot shallconsist of 3000 ft 1000 m,or fraction thereof,of the samegrade and size chain.If a continuous length of chain exceeds3000 ft 1000 m,it shall also be considered a lot.3.1.3proof test,nquality control tensile test applied tochain for the purpose of verifying weld and material quality.3.1.3.1 DiscussionIt is the minimum force in pounds ornewtons which the chain has withstood at the time it left theproducer,under a test in which a constantly increasing forcehas been applied in direct tension to a straight length of chain.Proof test loads are a manufacturing integrity test and shall notbe used as criteria for service or design purposes.3.1.4 working load limit(WLL),nmaximum combinedstatic and dynamic load in pounds or kilograms that shall beapplied in direct tension to an undamaged straight length ofchain.4.Ordering Information4.1 It shall be the responsibility of the purchaser to specifyall requirements that are necessary for material ordered underthis specification.Such requirements may include,but are notlimited to,the following:4.1.1 Product to conform to Specification A413 or A413Mand date of issue,4.1.2 Grade of chain,4.1.3 Nominal size of chain(in.or mm),4.1.4 Quantity of chain(ft or m),4.1.5 Length of each piece,if required,4.1.6 Finish,if required,4.1.7 Certification of test(s),if required,and4.1.8 Acceptance of inspection by purchaser,if required.5.Material Requirements5.1 Heat AnalysisThe selection of the steel is left to thejudgment of the individual chain manufacturer provided thesteel meets the following criteria:1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.27 on Steel Chain.Current edition approved Nov.1,2012.Published November 2012.Originallyapproved in 1957.Last previous edition approved in 2007 as A413/A413M 07.DOI:10.1520/A0413_A0413M-07R12.2For 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 Carbon,max,%0.370Phosphorus,max,%0.048Sulfur,max,%0.0585.2 Product AnalysisThe steel used may be analyzed bythe purchaser and shall conform to the requirements of 5.1subject to the product analysis tolerances specified in Specifi-cation A29/A29M.Test samples may be taken from rods,bars,or finished chain.Samples for analysis shall be so taken as torepresent the full cross section of the specimen.5.3 Test Methods,Practices,and Terminology A751 shall beused for referee purposes.6.Manufacture6.1 Welding ProcessCarbon steel chain may be made bythe forge welding,electric welding
