Alloy 2205 Duplex Pipe
2205 alloy duplex pipe is a stainless steel seamless pipe with excellent corrosion resistance and high strength.
2205 alloy duplex pipe contains about 40-50% ferrite and has good corrosion resistance, chloride stress corrosion cracking resistance and high strength in the annealed state. Compared with 316/316L and 317L stainless steel, 2205 stainless steel has better corrosion resistance. In addition, 2205 stainless steel also has excellent processing and welding properties, and is easy to process into seamless pipes of various shapes and sizes.
