| 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. |
