S32750

S32750 Stainless Steel

Super Duplex | UNS S32750 | 1.4410

Super Duplex UNS S32750 has excellent corrosion resistance in a wide variety of corrosive media making it ideal for use in environments exposed to the harshest chemical conditions.
It has outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with Critical Pitting Temperature exceeding 50°C.
Compared to austenitic and 22%Cr duplex stainless steels, UNS S32750 is of higher strength and even more suitable in situations where it will be exposed to extremely high stresses.
This combined with its excellent ductility and impact strength at both ambient and sub-zero temperatures further increases its appeal as the ultimate super duplex grade.
High resistance to abrasion, erosion and cavitation erosion combined with excellent resistance to stress corrosion cracking in chloride containing environments makes UNS S32750 perfect for use in the Oil and Gas Industries where subsea equipment is subject to some of the harshest chloride containing conditions in the world.
UNS S32750 is listed in NACE MR 01 75 for sour service for its suitability of use for oilfield equipment where sulphide stress corrosion cracking may be a risk in hydrogen sulphide (sour) environments.
UNS S32750 is also ASME Approved for Pressure Vessel applications.
