Duplex 2205 Pipe

Duplex 2205 pipe

What is a Duplex 2205 Pipe?

Duplex grades of stainless steel have a stunning composition of austenite and ferrite microstructures (50, 50). A duplex 2205 pipe contains 22% chromium and 5% nickel with molybdenum and nitrogen. It has terrific strength, workability, and long service duration with low maintenance requirements.

Is 2205 Stainless tube better than 316?

Both these materials contain molybdenum and get used widely in corrosive and marine environments. However, 316 piping derives from an 18-8 composition of chromium and nickel, unlike the 22-5 proportion of a duplex 2205 stainless steel pipe. Duplex materials show higher yield strength and better corrosion resistance when exposed to chlorides, acids, and sulphides.

On the flip side, duplex piping can face embrittlement over 300°C. But 316 can comfortably work at temperatures up to 760°C.
