Grade 120 Chain

Grade 120

Grade 120 chain is a high-strength alloy steel chain that outperforms Grade 80 and Grade 100 chains in terms of load-bearing capacity and durability. Unlike Grade 80 and Grade 100 chains, which are designed to stretch before they break as a safety feature are more susceptible to nicks. pits and gouges. The Grade 120 chain has significantly less elasticity. This means it doesn’t stretch as much and is more resistant to damage from nicks, pits, and gouges. Its increased toughness and reduced stretch make it ideal for demanding lifting and rigging applications like cold water or cold weather environments.
