Description
G80 lifting chain is a high-strength alloy steel chain, which is mainly used for lifting, hoisting, traction, bundling and other heavy-duty operations. With high strength, high toughness and good wear resistance, G80 chain is one of the common lifting chains in modern industry, especially suitable for high-risk scenarios and heavy-duty applications.
Material: High quality alloy steel 20Mn2
Surface treatment: natural, polished, blackened, sprayed, electro-galvanized and hot-dip galvanized, etc.
Production standard: GB/T 20947 (IDT) IS03077, EN818
Quality grades: G80, G100
Safety factor: 4 times
Logo: Conventional typing G80 can be typed according to customer requirements, and conventional non-standard can be produced.
Peculiarity
G80 chains are usually made of high-strength alloy steels (such as 20Mn2, 25MnV) and undergo heat treatments (such as quenching and tempering) to improve their hardness and strength. It can be used with various hooks, chain links, rigging and other accessories.The actual measurement of the chain link diameter meets the specification requirements.
