Super Duplex UNS S32750 combines 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 S32750 a 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 S32750 and having gained ASME Approval for Pressure Vessel applications it can be used in a wide variety of applications.

Duplex 2507 is a super duplex stainless steel developed for applications that demand high strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content causes high resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

Using Duplex 2507 must be restricted to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.
Duplex 2507 has good mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting weight savings can considerably reduce the overall cost of fabrication.

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
