Stainless Steel 442 Washers are crafted from a high-chromium ferritic stainless steel that contains about 17–18% chromium, along with low carbon and carefully controlled levels of silicon and manganese. This unique composition provides excellent resistance to oxidation and stability at high temperatures. On the mechanical side, SS 442 offers impressive hardness, good tensile strength, and exceptional wear resistance, making it ideal for abrasive and high-heat situations. Its ferritic structure not only ensures magnetic properties and dimensional stability but also maintains corrosion resistance in mildly corrosive environments. These combined traits enable SS 442 Washers to perform reliably under continuous thermal cycling and mechanical stress.
