Duplex Steel 2205 Coils are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and controlled nitrogen, creating a dual-phase ferritic-austenitic microstructure. This well-balanced composition provides the coils with exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, Duplex 2205 boasts high tensile and yield strength, impressive fatigue performance, and robust impact toughness. These coils maintain their stability even under high pressure and fluctuating temperatures, making them significantly stronger and more durable than many traditional stainless steels, ensuring outstanding performance in demanding industrial settings.
