Super duplex steel UN32760

Product Details:

Containing 25% chromium, 7% nickel, 3.6% molybdenum as well as copper, tungsten, and nitrogen, UNS S32760 is a highly alloyed super duplex stainless steel with high PREN for use in aggressive environments.

This is a super duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition. The super duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades. It is not uncommon to see the metal used as a practical solution to chloride-induced stress cracking, which is the Achille’s’ heel of stainless steel.

It also has outstanding resistance against sulphide-stress corrosion cracking in sour-gas environments.

Well known for its high impact strength, UNS S32760 displays no ductile-brittle transition but only a slight reduction in impact energy as temperature decreases. Even when welded, UNS S32760 displays only slightly lower impact strength.

It was initially developed as a seawater resistant material for pump applications in the North Sea. Following its success, it became the desired material for a wide range of uses including oil and gas applications, seawater, subsea pipework systems, heat exchangers and more.
