DP3W is part of a family of super duplex stainless steels with pitting resistance equivalents (PRE) equal to or greater than 40 and highly alloyed with chromium, molybdenum, nitrogen and tungsten. They resist localized corrosion in aggressive chloride-containing environments and have application in oil country tubular goods (OCTG). This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-573. Producer or source: Sumitomo Metal Industries Ltd.
