Super Duplex Steel Washers are produced from a balanced mixture of austenitic and ferritic stainless steel, with high concentrations of chromium (25-28%), molybdenum (3-5%), and nitrogen. This special composition has outstanding resistance to corrosion, particularly from chloride stress corrosion cracking. Such washers have high tensile strength, generally as much as 850 MPa, and outstanding toughness and resistance to pitting and crevice corrosion. The two-phase microstructure increases both durability and strength and makes them more superior than regular stainless steel washers in harsh environments.
