Duplex Steel 2205 Tubing is made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and controlled nitrogen, creating a dual-phase microstructure of ferrite and austenite. This well-balanced composition offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, Duplex 2205 boasts high yield and tensile strength, excellent fatigue resistance, and good toughness, even in low temperatures. The tubing remains exceptionally stable under high pressure and fluctuating temperatures, making it more resilient than many traditional stainless steels and perfect for tough industrial operating conditions.
