Super Duplex Steel Washers are composed of a balanced mixture of austenitic and ferritic stainless steel structures, containing elements such as chromium (24–26%), molybdenum (3–5%), and nickel (6–8%). This composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these washers offer high tensile strength, good ductility, and superior impact resistance. They maintain excellent performance in both high-pressure and high-temperature environments, making them suitable for aggressive industrial applications where both strength and corrosion resistance are critical.
