Material summary

Super duplex steel UNS S32760 is one of the most common super duplex steel grades on the market. UNS S32760 is a duplex steel specially designed for use in corrosive chlorine-containing environments and has increased W and Cu compared to UNS S32750. It has very good resistance to localized corrosion and stress corrosion cracking and has high mechanical strength.

Stainless steel grade S32760 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 S32760 can be easily machined and welded.
