Duplex steel is a type of stainless steel that is characterized by its high strength and excellent corrosion resistance. It is a two-phase microstructure that consists of both austenitic and ferritic grains. This unique combination of microstructures results in a material with superior properties when compared to traditional austenitic and ferritic steels.
The element composition of duplex steel varies depending on the grade of the material. Generally, it consists of around {{0}} percent chromium, 4-7 percent nickel, and 0.2-0.3 percent nitrogen. Other elements such as molybdenum, copper, and tungsten may also be added to improve specific properties of the material.

As you can see, duplex steel has a high tensile strength and yield strength, which makes it suitable for use in high-stress applications. It also has a good elongation percentage, which means that it can be formed into various shapes without cracking or breaking. Finally, its hardness is comparable to that of other types of stainless steel, making it resistant to wear and tear.
Flanges: Duplex steel flanges are used to connect pipes or fittings together. They are available in various sizes and types, including slip-on, weld-neck, and more.
