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 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.
