ASTM International Standard Specification for Machine and Coil Chain ASTM A467/A467M-07(2012)

This specification covers welded carbon steel machine chain and coil chain. Although these chains are not intended for pocket wheel use, they can be used for pocket and sprocket wheel use. There are two classes each of machine and coil chain: class MS which are machine, straight-link steel chains; class MT which are machine, twist-link steel chains; class CS which are coil, straight-link chains; and class CT, which are coil, twist-link steel chains. The steel shall be made by the open-hearth, electric-furnace, or basic-oxygen process. Classes MS, MT, CS, and CT shall be electric welded. All chain in classes MS and CS shall be subjected to proof test and all chain classes shall undergo a breaking force test.
