Introduction to Duplex Steel
Duplex steel is a type of stainless steel that combines the advantages of 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, excellent corrosion resistance, and good weldability. These properties make duplex steel widely used in various industries, such as oil and gas, chemical processing, marine engineering, and desalination plants. In China, there are many excellent factories that produce high - quality duplex steel products. Here are the top 10 duplex steel factories in China in 2026.
