Duplex steel is an alloy material. It is usually composed of iron, carbon, and other alloying elements (such as chromium, nickel, molybdenum, etc.)Duplex steel gets its name because it consists of two different organizational phases (austenite phase and ferrite phase), which provide excellent strength and toughness properties and are commonly used to make a variety of parts and components with high strength requirements,The organization of this alloy is relatively more complex than that of single-phase steels, which provides better properties.Overall, duplex steel is a highly corrosion-resistant and superior-performing material suitable for use in various industrial sectors.
