PRODUCT DETAILS
Description
Duplex Stainless Steel (DSS) including grades duplex 2205(S31803) and super duplex, they are commonly consist of 50% ferrite and 50% austenite, and generally requires not less than 30%. Duplex stainless steel has good welding performance and high strength. Compared with austenitic stainless steel, it is about double yield strength of stainless steel 316, 317 etc., it make the equipment lighter and stronger. Duplex stainless steel pipe has very good resistance to localized corrosion and stress corrosion cracking. Duplex steel is not intended to be used at temperatures above 300°C due to embrittlement, the continuous use temperature is from -50 to 250 °C.
Typical Properties:
Low cost
Alternative to high nickel based alloys
High strength
Corrosion resistant
Very hard machining
Applications
2205, used in chemical processing, oil and gas processing equipment, marine and other high chloride environments, effluent scrubbing systems, pulp and paper industry, cargo tanks for ships and trucks, food processing equipment, biofuels plant.
2304, used in chloride containing environments, welded pipe systems, transportation, heat exchanger tubes, construction, pressure vessels, caustic solutions and the food industry.
