Duplex Steel 2205 Sheets and Plates are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and controlled nitrogen, creating a well-balanced ferritic-austenitic microstructure. This unique composition offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich settings. On the mechanical side, Duplex 2205 boasts high tensile and yield strength, excellent fatigue resistance, and good impact toughness. These sheets and plates remain stable under high pressure and fluctuating temperatures, making them stronger and more durable than conventional austenitic stainless steels.
