Introduction to Duplex Steel
Duplex steel is a type of stainless steel that combines the beneficial properties of austenitic and ferritic stainless steels. It has a two – phase microstructure consisting of approximately equal proportions of austenite and ferrite. This unique structure endows duplex steel with high strength, good corrosion resistance, and excellent weldability. It is widely used in various industries such as oil and gas, chemical processing, marine engineering, and desalination plants due to its ability to withstand harsh environments and heavy loads.
