18Cr-2Ni Duplex Stainless
metalThis is a duplex stainless steel with elevated cobalt and silicon content alongside chromium and nickel, representing a modified composition within the duplex family. The material is designed for high-strength applications requiring corrosion resistance, with the dual-phase microstructure (austenite + ferrite) providing a balance of strength and toughness that distinguishes it from single-phase austenitic or ferritic stainless steels. Industrial applications include chemical processing equipment, pressure vessels, and marine/offshore structures where both corrosion resistance and load-bearing capacity are critical; the elevated cobalt addition suggests potential use in specialty tooling or high-temperature service environments where enhanced hardness or wear resistance is needed alongside corrosion protection.
