UNS S32205 is the representative grade of super duplex stainless steel based on 26% chromium and 6% nickel composition. S32550 is designed for high strength occasion where need good resistance to chemical corrosion and attack from seawater due to it has very good pitting and crevice corrosion resistance resulting from a controlled addition of copper. Alloy S32205 is suitable for use in seawater and other chloride-containing environments.
