Super Duplex S32760 Features:

Super Duplex stainless steel S32760 (UNS S32760, DIN 1.4501, ASTM F55) was originally developed as Zeron 100 by the UK company Mather & Platt in the 1970s. It contains a slightly higher copper and tungsten content compared with S32750. UNS S32760 contains 25% chromium, 7% nickel, 3.6% molybdenum as well as copper, tungsten, and nitrogen. This is a super duplex grade with a ferritic-austenitic microstructure. 


Stainless steel grade F55 has excellent corrosion resistance to a wide range of areas, especially resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with critical pitting temperature that is more than 50°C (122°F). This material is known to also have high strength and extended lifecycle. It is 10% lighter than grade 316 steel, ideal for sub-zero service, and more cost effective than nickel alloys. Stainless steel grade F55 can be easily machined and welded.
