Grade 80 Alloy Steel Short Link Chain EN818-7 Round Link Steel Chain
EN818-7 hoist chain is lifting short link chains, which is used for chain hoist, lever hoist and electric chain hoist etc. We use high qualified alloy steel to produce hoist chains (Mn alloy steel), all hoist 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:BS EN818-7
Chain grade:G80
