Duplex Steel S32205 tubing is a top-notch stainless steel product known for its impressive dual-phase microstructure, which combines austenite and ferrite. This unique blend gives it remarkable mechanical strength, exceptional resistance to corrosion, and outstanding durability, even in tough environments. It’s particularly tough against pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, making it a go-to choice for industries like chemical processing, petrochemical, oil and gas, and marine applications where both strength and corrosion resistance are essential.
Typically, Duplex Steel S32205 tubing contains about 22–25% chromium, 4–7% nickel, 2–4% molybdenum, and nitrogen, all of which boost its corrosion resistance and mechanical performance. It boasts a tensile strength of around 620–850 MPa and a yield strength of about 450–550 MPa, along with excellent ductility, toughness, and fatigue resistance. The balanced duplex microstructure also ensures thermal stability and guards against intergranular corrosion, making this tubing a reliable option for high-pressure and high-temperature situations.
