Abstract
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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers carbon steel chain for such applications as railroad cars, construction, industrial uses, load binding, and general purposes other than overhead lifting.
Note 1???
This specification does not cover carbon steel chain for sprocket applications. 1.2 Three classes of carbon steel chain are covered:
1.2.1 Grade 30???Proof coil chain.
1.2.2 Grade 43???High test chain.
1.2.3 Grade 70???Transport chain.
1.3 The Grade designation is 1/10 of the minimum breaking strength 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 in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
