2205 Stainless Steel Pipe

2205 stainless steel pipe & tube is widely used in many industries, like oil & gas, paper marking e.g, requiring high strength and excellent corrosion resistance, stainless, 2205 is often used as an alternative of UNS S31803/S32205, the EN steel no. 1.4462, DIN X2CrNiMoN 22-5-3.

205 duplex (Austenitic-Ferritic) stainless steel contain 22% chromium, 5% nickel, 3.2% molybdenum and other alloying elements such as nitrogen and manganese, the high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317L.
