This specification deals with Grade 80 heat-treated alloy steel chain for applications such as slings, lifting assemblies, and load binding. The alloy steel chain shall be made to a fully-killed fine austenitic grain process. Alloy steel chain may be made by the electric welding or gas welding process. The material shall be heat treated which includes quenching and tempering. Material's composition shall conform to the chemical requirements for carbon, phosphorous, sulfur, nickel, chromium, and molybdenum. The material shall conform to the mechanical property requirements for breaking force and elongation and to the dimensional requirements for the appropriate size chain. All chain shall be tested to at least the proof load.

ORDER

Scope

1.1 This specification covers Grade 80 heat-treated alloy steel chain for such applications as slings, lifting assemblies, and load binding.

Note 1This specification does not cover alloy steel chain for pocket wheel applications.

1.2 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.

1.3 The values stated in either SI 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.
