ASTM90 Stainless Steel Link Chains
These stainless steel chain manufacturing standards refer to ASTM 80, NACM 84/90, and NACM 96. Its quality class reaches G43. The minimum safety factor of the G43 chain is 2 times the working load.
Each link is processed in a continuously working heat treatment system to maintain a consistent and uniform hardness and strength among each link. Whether stainless steel or mild steel chains, Grade 43 chains have greater tensile strength than anti-roll chains. G43 chain typically has a 50% higher working load than the G30 chain. It is commonly used in agriculture, industry, construction, and transportation. Proof testing is provided for all chains produced by Titansuhe. We also support customization of chains that different from normal standards.
