1、Designation: A 467/A 467M 01 (Reapproved 2006)Standard Specification forMachine and Coil Chain1This standard is issued under the fixed designationA 467/A 467M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revisi

2、on. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers welded carbon steel machinechain and coil chain.Although these chains are not intended forpocket wheel

3、 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, straigh

4、t-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 m

5、ust beused independently of the other, without combining values inany way.2. Referenced Documents2.1 ASTM Standards:2E30 Test Methods for Chemical Analysis of Steel, CastIron, Open-Hearth Iron, and Wrought Iron33. Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 breaking force, mi

6、nimumthe minimum 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. This test is amanufacturers attribute acceptance test and shall not be usedas criteria for service.3.1.2

7、 lotfor 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 liftingthat process of lifting that wouldelevate a freely sus

8、pended load such that dropping the loadwould present a possibility of bodily injury or propertydamage.3.1.4 proof testa quality control tensile test applied tochain for the purpose of verifying weld and material quality. Itis the minimum force in pounds or newtons which the chainhas withstood at the

9、 time it left the producer, under a test inwhich a constantly increasing force has been applied in directtension to a straight length of chain. Proof test loads are amanufacturing integrity test and shall not be used as criteria forservice or design purposes.3.1.5 working load limit (WLL)the maximum

10、 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 specificatio

11、n. 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 required,4.1.7

12、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 Steel,Stainl

13、ess Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.27 on Steel Chain.Current edition approved May 1, 2006. Published May 2006. Originallyapproved in 1964.

Chemical Requirements6.1 Product AnalysisThe material used shall conform tothe following chemical requirements:Elements, max, %Classes MS, MT,CS, and CTCarbon 0.37Phosphorus 0.048Sulfur 0.0586.2 The analysis may be made

16、 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 E30shall be used.7. Mechanical Properties Requirements7.1 Proof TestAll chain in Classes MS and CS shall beproof tested to at least the

17、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 withstanding the prooftest load shall be removed from the chain.NOTE 1Chain Classes MT and CT do not require

18、 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 least the number of links specified in7.3.1.7.2.2 Fixtures for securing chain in a testing machine shallbe

19、 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 fixture shall not be considered part of the test specimen.NOTE 2U-bolts of the same or larger diameter and t

20、he 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 requirements as prescribed inTables 1-4 for their respective sizes and classes.7.3 Elongation:7.3.1 The

21、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 determining the original gauge length(L0).7.3.3 The elongation shall be based on the total extension atfrac

22、ture. 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 side scale.Elongation %! 5 $DL/L$0% % 3 100where:DL = test specimen final length at fracture test speci-me

23、n 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 be a minimum of 10 %.7.4 One test for breaking strength and elongation shall bemade from each lot. The elo

24、ngation 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 Tables 1-4 for the appropriate class and sizechain. Inside widths and lengths are not to exceed 65 % fromth

25、e 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 of3 %. Oversized wire may be used for all applications.9. Workmanship, Finish, and Appearance9.1 The chain

26、 at the time of shipment shall be free ofdiscontinuities that would prevent the chain from enduring theworking load limit forces.9.2 The manufacturer may apply a surface treatment orcoating of his own choice for identification or corrosionresistance unless the customer specifies otherwise.10. Retest

27、s10.1 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 satisfactory,the chain will be considered acceptable.TABLE 1 Machine ChainStraight Link(Not to be used in overhead lifting appl
