Detailed Description
S31803, GB 00Cr22Ni5Mo3N, is a duplex stainless steel, 2205 alloy (UNS S32305/S31803) is 22% chromium, 3% Mo and 5-6% nickel alloy composition of nitrogen duplex stainless steel. It has high strength, good toughness and good global and local co-strong corrosion resistance. With the 316L and 317L austenitic stainless steel compared to 2205 alloy in terms of corrosion and crack damage spots superior performance, it has high corrosion resistance, compared with the austenite, its lower coefficient of thermal expansion, thermal conductivity is higher. Application: Pressure vessels, pressure storage tanks, high pressure piping, heat exchangers (chemical processing industry). Oil and gas pipelines, heat exchangers, fittings, etc. Concentrated nitric acid in seawater temperature heat exchangers and condensers and accessories. Sewage treatment system
