Details Alloy steel chains are commonly used because of their strength, durability, abrasion resistance and ability to match the load shapes that use them.



In addition, these sling can enhance the thermal material. Level 80 heat treatment alloy steel chain, suitable for sling, starting recombinant parts and load binding applications. The alloy steel chain is made by welding or gas welding process. The material should be heat-treated, including quenching and tempering. The composition of the material should conform to the chemical requirements of carbon, phosphorus, sulfur, nickel, chromium and molybdenum. The material shall meet the mechanical performance requirements of fracture force and elongation and the size requirements of the appropriate size chain.



All chains should be tested for at least test loads.



1) Material: High quality alloy steel 20mn2



2) Size: 6mm,7mm,8mm,9mm,10mm,12mm,13mm,14mm,16mm,18mm,20mm,22mm,24mm



3) Surface treatment: its own color, polishing, black, plastic coating, hot-dip galvanizing, galvanizing and so on.



4) Manufacturing Standards: En818-2,iso,din 764,din 766,din 763,din 5685a/c,bs,jis,astm 80,nacm 84/90,NACM 96,



5) Quality level: G80,g43



6) Safety factor: G80 minimum 4 times, G43 minimum 2 times



7) Product marking: 8,G80 is used for identification purposes, or as required.



8) Packaging: steel barrels, iron trays, sacks, wooden cases, plastic boxes and so on.



9) We can also make non-standard chains according to customer requirements.



10) Use: Gourd chain, binder chain, bundled chain, tie chain, transport chain, transmission, construction, jump decoration, swing, fishing, lifting chain, hardware chain, elevator balance chain, etc. The 30-stage chain is equipped with galvanized to provide a certain amount of corrosion resistance.



It is a lightweight chain, but suitable for many applications in general industry, agriculture and homeowners. The 43-stage (high test) galvanized chain has excellent corrosion resistance. It is about 50% stronger than the 30-stage chain and is suitable for many applications in general industry, agriculture and homeowners.
