Designation:A467/A467M07(Reapproved 2012)Standard Specification forMachine and Coil Chain1This standard is issued under the fixed designation A467/A467M;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.1.Scope*1.1 This specification covers welded carbon steel machinechain and coil chain.Although these chains are not intended forpocket wheel use,they can be used for pocket and sprocketwheel use.This chain shall never be used for overhead liftingapplications.1.2 There are two classes each of machine and coil chain:1.2.1 Class MSMachine,straight-link steel chain,1.2.2 Class MTMachine,twist-link steel chain,1.2.3 Class CSCoil,straight-link chain,and1.2.4 Class CTCoil,twist-link steel chain.1.3 The values stated in either inch-pound units or SI unitsshall be regarded separately as standard.Within the text,the SIunits are shown in brackets.The values stated in each systemmay not be exact equivalents;therefore,each system must beused independently of the other,without combining values inany way.2.Referenced Documents2.1 ASTM Standards:2A751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel Products3.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 representative testing to break when a constantlyincreasing force 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.3.1.3 overhead lifting,nprocess of lifting that wouldelevate a freely suspended load such that dropping the loadwould present a possibility of bodily injury or propertydamage.3.1.4 proof test,nquality control tensile test applied tochain for the purpose of verifying weld and material quality.3.1.4.1 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.3.1.5 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 to be considered include,but are not limited to,the following:4.1.1 ASTM Specification A467/A467Mand year of issue,4.1.2 Trade size of chain,4.1.3 Class of chain,4.1.4 Quantity of chain in feet or metres,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.Manufacture5.1 Melting Process The steel shall be made by theopen-hearth,electric-furnace,or basic-oxygen process.5.2 Welding Process Classes MS,MT,CS,and CT shallbe electric welded.6.Chemical Requirements6.1 Product Analysis The material used shall conform tothe following chemical requirements: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 1964.Last previous edition approved in 2007 as A467/A467M 07.DOI:10.1520/A0467_A0467M-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 Elements,max,%Classes MS,MT,CS,and CTCarbon0.37Phosphorus0.048Sulfur0.0586.2 The analysis may be made by the purchaser from thebars or finished chain.Samples for analysis shall represent thefull cross section of the specimen.6.3 For referee purposes,Test Methods,Practices,andTerminology A751 shall be used.7.Mechanical Properties Requirements7.1 Proof TestAll chain in Classes MS and CS shall beproof tested to at least the proof load prescribed in Table 1 andTable 2 for the appropriate size and class chain.When sotested,it shall withstand these loads without los
