Super duplex Stainless Steel refers to a duplex steel with PREN>40, containing 25% Cr, high molybdenum (>3.5%), and high nitrogen (0.22%-0.30%). The main grades are UNS S32550 (UR52N+), S32750 (SAF 2507) and S32760 (Zeron 100), which were developed by French CLI, Swedish SANDVIK and British MATER+PLATT. Their deformed materials were launched in 1990 and 1991 respectively, and entered the market in recent years. The composition of these three steels is similar, the difference is the different content of tungsten and copper.
