Due to the characteristics of the two-phase structure 
and proper control of the chemical composition and heat treatment process, duplex stainless steel (DSS) takes advantage of both stainless steels, with excellent toughness and weldability and great strength and resistance to chloride stress corrosion。
Its yield strength is 2 times greater than that of ordinary stainless steel, which enables you to reduce the cost of equipment manufacturing. Duplex stainless steel has much better resistance performance to pitting & crevice corrosion, stress corrosion and anti-fatigue corrosion performance than ordinary austenitic stainless steel particularly in the harsh environment (such as seawater, chloride with high ion content). Duplex stainless steel can be widely used in the machine & equipment relative on oil refining, fertilizer, paper, oil, foundry, heat exchangers,cold leaching as well as other devices.
