Duplex Steel 2205 bars are robust stainless steel products known for their unique dual-phase microstructure, which combines austenite and ferrite. This clever mix offers a fantastic balance of mechanical strength, toughness, and resistance to corrosion. These bars stand up remarkably well against pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, making them perfect for tough environments like chemical processing, oil and gas, marine, and petrochemical industries. Their outstanding mechanical and corrosion-resistant qualities guarantee dependable performance in both structural and high-pressure settings.

Typically, Duplex Steel 2205 bars contain about 22–25% chromium, 4–7% nickel, 2–3% molybdenum, and nitrogen, all of which boost their strength and resistance to corrosion. They boast a tensile strength of around 620–850 MPa and a yield strength of about 450–550 MPa, along with impressive toughness, ductility, and fatigue resistance. The balanced duplex microstructure also ensures thermal stability and guards against intergranular corrosion, making these bars suitable for high-temperature and chemically aggressive conditions.
