Introduction to Duplex Stainless Steel
Duplex stainless steels are a family of stainless steels that have a two – phase microstructure consisting of roughly equal amounts of ferrite and austenite. This unique microstructure provides them with a combination of the beneficial properties of both ferrite and austenite stainless steels. Duplex Stainless Steel
Compared to austenitic stainless steels, duplex stainless steels generally have higher strength, which allows for the use of thinner sections in engineering applications, reducing weight and cost. They also exhibit excellent resistance to stress – corrosion cracking, a common problem in many corrosive environments. In contrast, compared to ferritic stainless steels, duplex stainless steels have better ductility and toughness, especially at low temperatures. These properties make duplex stainless steels suitable for a wide range of applications, including oil and gas, chemical processing, desalination plants, and architectural structures.
