Introduction to Duplex Steel
Duplex steel is a type of stainless steel that combines the properties of austenitic and ferritic stainless steels. It has a two – phase microstructure consisting of roughly equal amounts of ferrite and austenite. This unique structure gives duplex steel a remarkable combination of high strength and good corrosion resistance. Duplex Steel
Compared to austenitic stainless steels, duplex steel has higher yield strength, which means it can withstand greater stress without deforming. At the same time, it offers excellent resistance to stress – corrosion cracking, pitting, and crevice corrosion, making it suitable for a wide range of applications in harsh environments such as the oil and gas industry, chemical processing, and marine engineering.
