A32750 Properties Introduction
Alloy S32750(F53.2507) is a super duplex stainless steel made of 25% Cr,4% Mo,7% Ni and its composition added with W element. Mainly used in application of Chemical industry, Petra-chemical, and offshore equipments with special high tensile and corrosion-resistant ability.
Super Duplex alloy UNS S32750 (F53 / 1.4410 / Alloy 32750 / Alloy 32750) 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, with Critical Pitting Temperature exceeding 50°C.
UNS S32750 (F53 / 1.4410 / Alloy 32750) exhibits 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 (F53 / 1.4401) and having gained ASME Approval for Pressure Vessel applications Alloy 32750 can be used in a wide variety of applications.

Super Duplex Applications
Oil and gas industry equipment, Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems, Chemical process industries, heat exchangers, vessels, and piping, Desalination plants, high pressure RO-plants and seawater piping, Mechanical and structural components, high strength, corrosion-resistant parts, Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping.
Super Duplex Corrosion Resistance
The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.
The pitting Resistance equivalent of Super Duplex, calculated by PREN = Cr + 3.3Mo + 16N, will exceed 40 in most material forms.
