Introduction to Duplex Steel
Duplex steel is a type of stainless steel that combines the beneficial properties of both austenitic and ferritic stainless steels. It has a two - phase microstructure, consisting of approximately equal amounts of austenite and ferrite. This unique structure endows duplex steel with high strength, good corrosion resistance, especially against stress - corrosion cracking, and excellent weldability. These characteristics make duplex steel widely used in various industries such as oil and gas, chemical processing, marine engineering, and pulp and paper production. In China, the manufacturing of duplex steel has witnessed significant growth in recent years, with many companies emerging as global leaders in the production of high - quality duplex steel products.
