UNS S32760 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 Achilles’ heel of stainless steel.
Super Duplex UNS S32760 is among the most common super duplex grade in the market. Alloy 32760 is a super duplex stainless steel supplied in the hot worked and solution annealed condition. As a super duplex stainless steel, it combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >40, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C nb. versions of the PREN formula also include W as a positive influence on overall pitting resistance. It provides higher strength than both austenitic and 22% Cr duplex stainless steels, and is listed in NACE MR 0175 for sour service and ASME for pressure vessel applications. Alloy S32760 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.

Super Duplex Steel S32760 Round Bar is a type of stainless steel with excellent corrosion resistance. This material is often referred to as stainless steel rods or rebar. It has high resistance to pitting, intergranular corrosion, and chloride stress corrosion cracking. It also displays excellent thermal resistance and can withstand temperatures as high as 300 degrees. Super Duplex S32760 Bar is also a great choice for welding and can be produced by most standard methods.
Super Duplex Steel S32760 Round Bars have a wide range of applications. These rods and bars are widely used in oil and gas exploration, chemical processing, and in equipment. They are also used in pulp and paper digesters, paper machines, and liquor tanks. These steels have excellent corrosion resistance and exceptional strength. They are also good candidates for marine environments.
Super Duplex Steel S32760 Rods' excellent properties make them suitable for a wide range of industries. Such as oil and gas Offshore (topside and subsea applications), petrochemical, chemical, water treatment and desalination, paper and pulp, marine, and power generation industries. They are also useful in heat exchangers, process components, flowlines, pipelines, umbilicals, risers, and other sub-sea components.
