Stainless Steel 422 Washers consist mainly of iron with 11–12% chromium, 0.5% nickel, 0.5% molybdenum, and minute amounts of manganese, silicon, carbon, and vanadium. This composition provides a superior combination of strength, hardness, and resistance to heat. They have a tensile strength of around 620 MPa, yield strength of 450 MPa, and excellent fatigue resistance. SS 422 washers have mechanical stability at high temperatures, offer oxidation as well as scaling resistance, and are resistant to thermal cycling, hence ideal for structural integrity under severe conditions.
SS 422 Washers are widely applied in aerospace applications, such as jet engines and turbine components of aircraft, where anti-combustion fatigue and oxidation resistance is essential. In the power generation industry, they are used in gas and steam turbines due to their high-temperature performance and mechanical strength. They are also applicable to chemical processing equipment needing corrosion and wear resistance. Moreover, SS 422 washers find application in high-temperature fasteners, flange assemblies, and structural fixtures under harsh operating stresses, guaranteeing durability, safety, and performance consistency in vital industrial application.
