At Hazlewood Fasteners, we are proud to manufacture and supply Stainless Steel 442 Washers, engineered for strength, heat resistance, and durability. Designed to perform in extreme temperature and corrosive environments, these washers are ideal for heavy-duty industrial applications. Stainless Steel 442, a ferritic alloy, provides excellent resistance to scaling and oxidation, making it perfect for furnaces, boilers, and heat exchangers. Each washer is precision-made and rigorously tested to meet global quality standards. At Hazlewood Fasteners, we combine advanced engineering with consistent quality to deliver fastening components that perform reliably under heat, pressure, and time.
Stainless Steel 442 Washers are primarily composed of iron with about 18% chromium and small additions of manganese, silicon, and carbon. This ferritic stainless steel offers high resistance to heat, oxidation, and corrosion while maintaining great mechanical strength. The washers have a tensile strength of approximately 620 MPa and retain their hardness even at elevated temperatures. They exhibit good magnetic properties and thermal stability, ensuring reliable performance under cyclic heating. The alloy’s ability to resist scaling and thermal fatigue makes it ideal for long-term use in high-temperature environments.
