This specification covers carbon steel chain for such applications as railroad cars, construction, industrial uses, load binding, and general purposes other than overhead fitting. The three classes of carbon steel chains covered here include Grade 30 (proof coil chain), Grade 43 (high test chain), and Grade 70 (transport chain). The dimensional requirements of the chain with respect to the appropriate grade and size are presented. The mechanical testing requirements for the steel includes, proof testing, breaking force testing, and elongation testing. One test for breaking strength and elongation shall be made from each lot. The elongation and breaking force tests may be performed at the same time on the same test specimen.
