Super Duplex UNS S32750combines the most desirable characteristics of both ferritic and austenitic steels. It has excellent corrosion resistance to a wide variety of media, with outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments due to its high chromium, molybdenum, and nitrogen level, with Critical Pitting Temperature exceeding 50°C.
The duplex microstructure gives this grade high strength UNS S32750a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300°C.
Listed in NACE MR 01 75 for sour service UNS S32750and having gained ASME Approval for Pressure Vessel applications it can be used in a wide variety of applications.
