2205 Duplex Stainless Steel Tube
GNEE is one of the pioneers in providing Duplex 2205 Pipes, you can choose the right pipes and get the evaluation you want at the best price.
2205 stainless steel pipe is designed for applications where corrosion resistance is the main concern. It is more than twice as strong as traditional austenitic stainless steel in the annealed condition and exhibits better corrosion resistance than 316 alloy in many environments. Therefore, 2205 Duplex Pipe is the most widely used duplex stainless steel.
2205 pipe has a common name of UNS N31803. 2205 Duplex Stainless Round Pipe can be manufactured by seamless construction or automatic welding process, and no filler metal is required to be added to the alloy during the welding process.
