Made from a high-chromium ferritic stainless steel that contains around 23–27% chromium, along with small amounts of molybdenum and other stabilizing elements, Stainless Steel 446 Fasteners boast exceptional oxidation resistance at temperatures reaching up to 1100°C. They also perform well in sulfurous atmospheres and hot gases. These fasteners maintain good dimensional stability, have a density of about 7.8 g/cm³, and exhibit tensile strength between 485–620 MPa. While they may not be as strong at room temperature as austenitic grades, their excellent scaling resistance and performance in extreme temperatures make them ideal for specialized industrial uses.
Stainless Steel 446 Fasteners are widely utilized in industries that demand high-temperature and oxidation-resistant fastening solutions. They’re commonly found in furnace linings, burners, kilns, and heat treatment equipment, thanks to their ability to endure prolonged exposure to hot gases and oxidizing environments. The petrochemical and power generation sectors rely on them for thermal processing units and exhaust systems. Additionally, they are used in incinerators, chemical plants, and heat exchangers, where resistance to thermal cycling and corrosion is essential.
