Performance and comparison of 2205 duplex stainless steel seamless pipe:
2205 duplex steel pipe combines the most beneficial properties of ferrite and austenite, and has good resistance to chloride ion stress corrosion cracking. It is a duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. Yield strength is twice that of austenitic stainless steel.
This feature allows designers to reduce weight when designing products, making this alloy more advantageous than 316,317L. Because the steel has high chromium and molybdenum content, it has excellent resistance to pitting and uniform corrosion. The dual-phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.
