High corrosion-resistant and high strength UNS S32205 can withstand the brackish or salt water impact of a coastal flood surge. This quality along with long service life and low maintenance requirements led to the use of 2205 duplex stainless steel in pedestrian bridges.Duplex Stainless Steel - Plate, Sheet, Bar, Tubular nas 64 duplex stainless steel plate steelsDuplex Grades. Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Duplex stainless steel plate contains relatively high levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%).
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.AVESTA WELDING MANUALstainless steel technology.
