Application

Duplex steel application temperature range:-40 °C to 250 °C.Duplex steel compared to 

common austenitic stainless steel has:good resistance to chlorine ion corrosion 

resistance (usually pitting),good resistance to stress corrosion, close to two times the 

yield strength,thermal expansion coefficient is small, with carbon steel quite roughly,for the 

carbon steel duplex steel mixed used relatively advantageous occasion.
