STAINLESS STEEL TUBE & PIPE   

Super Duplex Alloy UNS S32760 (F55 / 1.4501) 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 S32760, F55, 1.4501 Super Duplex has enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types. This is due to the further additions of chromium, molybdenum, and nitrogen to these grades. UNS S32760, 1.4501 combines high strength and good ductility with outstanding corrosion resistance.

Providing higher strength than both austenitic and 22% Cr Duples Stainless Steel UNS S32760 (F55) is suited to a variety of applications in industries such as Chemical Processing, Oil & Gas, and Marine environments. Super Duplex Alloy UNS S32760 (F55 / 1.4501) 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.

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.
