1、Designation: A413/A413M 07 (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 n
2、umber 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 sucha
3、pplications as railroad cars, construction, industrial uses, loadbinding, and general purposes other than overhead lifting.NOTE 1This 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 Grad
4、e 43High test chain.1.2.3 Grade 70Transport chain.1.3 The Grade designation is110 of 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 rega
5、rded 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.

Heattreatment shall include quenching and tempering as describedin Terminology A941.7. Dimensional Requirements7.1 The
19、chain shall conform to the dimensional require-ments specified in Tables 1-3 for the appropriate grade and sizechain.7.2 DiameterThe diameter of the material from which thechain is manufactured shall not be smaller than the materialdiameter listed in Tables 1-3 within the following tolerance:7 %. Ov
20、ersized material may be used for all applications.8. Finish8.1 The manufacturer may apply a surface treatment orfinish of their own choice for identification or corrosionresistance unless the customer specifies otherwise. The surfacetreatment or finish shall not alter the chain in a manner thatwould
21、 cause the chain to not meet the other provisions of thisstandard.9. Mechanical Requirements9.1 Proof TestAll chain shall be tested to at least the proofload prescribed in Tables 1-3 for the appropriate grade and sizechain. When so tested it shall withstand these loads withoutloss of chain integrity
22、. Links or chain segments that do notwithstand the proof test load shall be removed from the chain.9.2 Breaking ForceThe breaking force test specimen shallconsist of a length from the lot containing at least the numberof links in Table 4. All chain that is heat treated shall be in thequenched and te
23、mpered condition before the breaking force ismeasured.9.2.1 Fixtures for securing chain in a testing machine shallbe properly designed to support securely the shoulder of thelink (see Note 2). The opening in the fixture shall not be morethan 125 % of the stock diameter being tested. Links engagedin
24、the testing fixture shall not be considered part of the testspecimen.NOTE 2“U” bolts of the same or larger diameter and the same orgreater strength may be used to secure the chain to the jaws of the testingmachine.9.2.2 Test specimens shall meet or exceed the minimumbreaking force values given in Ta
