Duplex Steel 2205 Coilis a stainless steel alloy recognized for its remarkable strength and resistance to corrosion. Its composition is roughly 22% chromium, 5-6% nickel, and 3% molybdenum, together with additional alloying elements. The term “duplex” points to its two-phase microstructure, made up of nearly equal amounts of austenite and ferrite phases. This distinctive structure delivers a blend of high mechanical strength, outstanding corrosion resistance, and good weldability.
