Made from a high-chromium ferritic stainless steel that contains about 23–27% chromium, along with small amounts of molybdenum and stabilizers for improved thermal and oxidation resistance, Stainless Steel 446 Washers maintain their shape and strength even at temperatures soaring up to 1100°C. They have a density of around 7.8 g/cm³ and a tensile strength that ranges from 485–620 MPa. While they may be less ductile at room temperature compared to austenitic grades, their excellent scaling resistance and durability during thermal cycling make them ideal for harsh industrial settings like kilns, incinerators, and exhaust systems.
These washers are widely utilized in industries that require fastening components capable of enduring high temperatures and corrosive environments. In furnace construction and heat treatment facilities, they secure structural components that are exposed to prolonged heat and oxidation. The petrochemical and power generation industries rely on them for use in burners, exhaust systems, and thermal processing units. Additionally, they find applications in chemical plants, kilns, and incinerators where resistance to sulfurous gases and thermal stress is essential. With their reliability and longevity, these washers ensure stable fastening solutions in conditions where performance is critical.
