Corrosion-resistant steels - Ferritic-austenitic (DUPLEX) steels (en-GB)

The ferritic-austenitic microstructure of duplex steels is achieved by balancing the alloying elements Chromium, Nickel, Molybdenum, Manganese and Nitrogen and results in higher yield strengths and improved resistance to stress corrosion cracking. Duplex steels are used in a variety of applications under highly corrosive conditions in a wide range of industries, e.g. Oil/Gas & CPI.
