UNS S32760 Super Duplex Stainless Steel

Super Duplex UNS S32760 / F55 / 1.4501 is among the most common super duplex grade in the market. UNS S32760 is duplex stainless steel specially designed for service in aggressive chloride-containing environments and has additions of W and Cu compared to UNS S32750. It has very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength.

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 an 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.
