S32760 super duplex Stainless Steel tube is developed to be used in aggressive environments. Properties of S32760 include toughness, high strength, corrosion resistance in a large number of organic and inorganic acids. Finally it features high resistance to strong alkalis and resists corrosion in a number of non-oxidizing acids.
While involving extended exposure to temperatures more than 572F use of S32760 is not recommended. The chemical composition of UNS S32750 and UNS S32760 are similar; however, the latter contains slightly more copper and tungsten. The copper content (min. 0.5, max 1.0) permits excellent resistance to corrosion in many non-oxidizing and mineral acids like hydrochloric and sulfuric acid.
Super Duplex Alloy UNS SS32760 (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.
Providing higher strength than both austenitic and 22% Cr Duples Stainless Steels UNS S32760 (F55) is suited to a variety of applications in industries such as Chemical Processing, Oil & Gas, and Marine environments. UNS S32760 (F55 / 1.4501) is listed in NACE MR 01 75 for sour service and having gained ASME Approval for Pressure Vessel applications.
