1、Designation: A467/A467M 07 (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.

2、 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 us

3、e, 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-l

4、ink 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

5、 beused independently of the other, without combining values inany way.2.

6、imum 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

7、.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 fre

8、ely 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

9、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 l

Ordering Information4.1 It shall be the responsibility of the purchaser to specifyall requirements that are necessary for material order

11、ed 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 Fin

17、ology 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 loss of chainint

18、egrity. Links or chain segments not withstanding 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

19、of a lengthfrom the lot containing at least 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

20、tested. Links engaged in thetesting fixture 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 sha

21、ll conformto the minimum breaking force 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 % o

22、f the proof testshall be applied for determining 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 ( L) divided by the original gauge length (L0). Theelongation may be determined by the equati

23、on below or byautographic recorder or side scale.Elongation %! 5 $L/L$0%3100where:L = test specimen final length at fracture test specimenoriginal 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.

24、2).7.3.4 The elongation shall be 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 dimensiona

25、l require-ments specified in Tables 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 a

26、nd Table 2 within a tolerance of7 %. 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 al

Retests10.1 If the original test specimen fails to conform to therequirements of 7.2.3, two additional test specimens from thesame lot may be tested. If both additional tests are satis
