G80 LIFTING CHAIN EN-818-2 BLACKENED

G80 LIFTING CHAIN EN-818-2 BLACKENED

EN818-2 Grade 80 lifting chain is lifting short link chains, through heat treated and hardened 38-42HRC, which is used for lifting purpose. We use high qualified alloy steel to produce G80 chains (Mn alloy steel), all G80 chains will be approved by 6-meter proof load test, breaking link rate is 1/10000, which exceed industrial level 6/10000.
