Duplex Stainless Steel

Duplex Stainless Steels are comprised of both austenitic and ferritic steel in nearly equal portions. This combination allows the alloy to be stronger and tougher than standard austenitic steels.  Duplex steel contains a high content of chromium and nitrogen, which allows the alloy to maintain good weldability and to be resistant to both corrosion and high stress corrosion cracking.
