ASTM NACM90(G43) High-strength Chain

 

Grade 43 chain is a steel chain that possess greater tensile strength than Proof Coil Chain. Grade 43 Chain typically has a 50% higher working load limit than Proof Coil or Grade 30 Chain. G43 chains are also referred to as High Test Chain.

Grade 43 is used in similar applications as Grade 30, but where greater working load limits are experienced. High Test Chain is used in agriculture, construction and the trucking industry.

All of our Grade 43 Chain is 100 percent Proof Tested.
