1、Designation: A 467/A 467M 07Standard Specification forMachine and Coil Chain1This standard is issued under the fixed designationA467/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 pare
2、ntheses indicates the year of last reapproval.A superscript epsilon (e) 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 u
3、sed 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.
4、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 independ
5、ently of the other, without combining values inany way.2. Referenced Documents2.1 ASTM Standards:2A 751 Test Methods, Practices, and Terminology forChemical Analysis of Steel Products3. Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 breaking force, minimum, nminimum force inpoun
6、ds 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
7、the purpose of acceptance testing, a lotshall consist of 3000 ft 1000 m, or fraction thereof, of thesame grade and size chain. If a continuous length of chainexceeds 3000 ft 1000 m, it shall also be considered a lot.3.1.3 overhead lifting, nprocess of lifting that wouldelevate a freely suspended loa
8、d 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 withsto
9、od 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),
10、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 spec
11、ification. Such requirements to be considered include,but are not limited to, the following:4.1.1 ASTM SpecificationA 467/A 467M and 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 require
12、d,4.1.7 Certification of test(s), if required, and4.1.8 Acceptance of inspection by purchaser, if required.5. Manufacture5.1 Melting ProcessThe steel shall be made by theopen-hearth, electric-furnace, or basic-oxygen process.1This specification is under the jurisdiction of ASTM Committee A01 on Stee
13、l,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.27 on Steel Chain.Current edition approved Nov. 1, 2007. Published November 2007.

Chemical Requirements6.1 Product AnalysisThe material used shall conform tothe following chemical requirements:Elements, max, %Classes MS, MT,CS
16、, and CTCarbon 0.37Phosphorus 0.048Sulfur 0.0586.2 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 A 751 shall be used.7. Mechanical
17、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 loss of chainintegrity. Links or chain segments not wit
18、hstanding the prooftest load shall be removed from the chain.NOTE 1Chain Classes MT and CT do not require proof testing sincethe twist operation is an adequate verification of link integrity.7.2 Breaking Force Test:7.2.1 The tension test specimen shall consist of a lengthfrom the lot containing at l
19、east the number of links specified in7.3.1.7.2.2 Fixtures for securing chain in a testing machine shallbe properly designed to securely support the shoulder of thelink (Note 2). The opening in the fixture shall not be more than125 % of the stock diameter being tested. Links engaged in thetesting fix
20、ture shall not be considered part of the test specimen.NOTE 2U-bolts of the same or larger diameter and the same or greaterstrength than the chain may be used to secure the chain to the jaws of thetesting machine.7.2.3 Test specimens from the finished chain shall conformto the minimum breaking force
21、 requirements as prescribed inTables 1-4 for their respective sizes and classes.7.3 Elongation:7.3.1 The elongation test specimen shall consist of a lengthfrom the lot containing at least the number of links in Table 5.7.3.2 A positive load not exceeding 10 % of the proof testshall be applied for de
22、termining the original gauge length(L0).7.3.3 The elongation shall be based on the total extension atfracture. This is expressed as a percentage of the change inlength (DL) divided by the original gauge length (L0). Theelongation may be determined by the equation below or byautographic recorder or s
23、ide scale.Elongation %! 5 $DL/L$0% % 3 100where:DL = test specimen final length at fracture test speci-men original gauge length L0, andL0 = original gauge length (sum or the inside lengths ofthe test chain links, not counting the fixture links, oras determined in 7.3.2).7.3.4 The elongation shall b
24、e a minimum of 10 %.7.4 One test for breaking strength and elongation shall bemade from each lot. The elongation and breaking force testsmay be performed at the same time on the same test specimen.8. Dimensional Requirements8.1 The chain shall conform to the dimensional require-ments specified in Ta
25、bles 1-4 for the appropriate class and sizechain. Inside widths and lengths are not to exceed 65 % fromthe nominal dimensions.8.2 DiameterThe diameter of the material from which thechain is manufactured shall not be smaller than the materialdiameter listed in Table 1 and Table 2 within a tolerance o
26、f7 %. Oversized wire may be used for all applications.9. Finish9.1 The manufacturer may apply a surface treatment orfinish of his own choice for identification or corrosion resis-tance unless the customer specifies otherwise. The surfacetreatment or finish shall not alter the chain properties in ama
27、nner that would cause the chain to not meet the otherprovisions of this standard.TABLE 1 Machine ChainStraight Link(Not to be used in overhead lifting applications)Trade Size Material DiameterWorking Load Limit,maxProof Test,Amin Breaking Force,AminNominal InsideLengthBNominal InsideWidthBmm in. mm
