Stainless duplex steel is a type of steel that exhibits high resistance to corrosion, particularly. This material is used primarily in industrial and maritime applications. Unlike regular steel, stainless steel is resistant to corrosion due to the special alloys present in its composition.
The term "duplex steel" signifies that stainless steel has two distinct microstructures. These microstructures are austenitic and ferritic in nature. These two structures enhance the material's resistance to corrosion. Austenitic structures contain alloys like chromium, nickel, and molybdenum, providing corrosion resistance. Ferritic structures, on the other hand, contain more chromium, increasing strength.
Stainless duplex steel possesses both austenitic and ferritic microstructures. Therefore, it combines high corrosion resistance with increased strength. Thanks to these properties, it is preferred in applications exposed to challenging environmental conditions such as chemical processes, maritime usage, petrochemical industry, water treatment plants, and food processing.
Stainless duplex steel offers higher strength and corrosion resistance compared to other stainless steels, making it widely used in various industrial and maritime applications.
