Products Description
Lork Group high-quality UNS S32205 is a chromium-nickel-molybdenum-nitrogen stainless steel. It is the most popular grade of duplex stainless steel and has a yield strength that is twice as high as that of austenitic stainless steel standard grades. UNS S32205 consists of around 40-50% ferrite in the annealed condition. The duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades.
UNS S32205 has superior resistance to chloride pitting and crevice corrosion as compared to 317L stainless steel. The alloy has outstanding corrosion resistance to seawater and most concentrations of sulphuric acid. In addition, UNS S32205 duplex stainless is also resistant to sulphide stress corrosion cracking (sour-gas environments).
