Duplex steel is celebrated for its unique composition, blending high levels of chromium and nickel with additions like molybdenum and nitrogen. This creates a robust metallurgical structure that combines the best features of austenitic and ferritic steels. The result is a material with outstanding mechanical properties, including remarkable tensile strength and impressive resistance to pitting and stress corrosion cracking, making it far tougher than many conventional stainless steels.
