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.
Providing higher strength than both austenitic and 22% Cr Duplex 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
S32760 super duplex stainless steel 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 S32750 and 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.
