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.
