Consider Donghua USA stainless steel chain for your toughest application. It is especially suitable when anti-corrosion properties are required, as in a chemical application or in extreme temperature conditions. Our austenitic stainless steel chain series has excellent anti-corrosion properties, and can be applied in acidic, alkaline and -40°-600° temperature conditions. In comparison, series 316L has better diamagnetism, good suitability in severe temperature conditions where anti-corrosion properties are needed. The martensitic stainless steel chain series (such as 2Cr13) has anti-corrosion properties as well as comparable strength to a chain with the same carbon steel content.

Donghua USA hoisting chain includes our standardized leaf chain series and multi-plate pin chain, as well as our parking garage chain and special leaf chain for stackers. Each adopts high wear-resistant pin carburizing technology andor pin through hardened technology in order to increase its impact resistance. An example is the special leaf chain for container stackers which has high wear resistance and fatigue performance in order to meet the requirements of high-load and continuous operation conditions.
