Super Duplex Stainless Steel

Material to UNS S32760 is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite.

The steel combines high mechanical strength (typically up to 600 MPa yield strength) and good ductility with outstanding corrosion resistance to marine environments and a wide, diverse range of oil & gas production environments. The alloy is supplied with a PREN(Pitting Resistance Equivalent) at >= 40.0 which guarantees high resistance to pitting corrosion. In addition, the steel offers high resistance to crevice corrosion and stress corrosion cracking.

Ambient and sub-zero (down to minus 50°C) notch ductility is good. These attributes mean that this super duplex steel can be used successfully as an alternative to 300 series stainless steel (such as type 316), standard 22% Cr duplex steel and precipitation hardening stainless steels. Where appropriate the alloy can be considered in lieu of more costly Grade 5 titanium or nickel based alloys.

Machinability & Welding

The machining and welding of this grade of super duplex stainless steel presents no particular problems. Guidance notes are available upon request.
