DIN5687 Standard is Germany Standard lifting short link chains, which is used for lifting purpose. We use high qualified alloy steel to produce G80 lifting chain (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.
Chain Material: 20Mn2A, 25MnV, 23MnNiCrMo54 etc
Production standard：DIN5687
Chain grade：Grade 80
Safety factor：6 meter breaking load test, 2.5 times proof load test, 4 times safety factor.
Surface treatment: black oxide, electroplate, black painted etc
