General scope. Both alloys combine the dual features of high strength and corrosion resistance obtained through the dual phase microstructure (50% austenite, 50% ferrite) associated with duplex stainless steels. UNS S32760 properties are slightly enhanced over S31803 by further additions of chromium (to 25%), and also tungsten and copper.
