Stainless Steel 446 Washers contain mainly iron with 23–30% chromium and traces of nickel and manganese. High chromium content provides substantial resistance to corrosion and oxidation at high temperatures up to 815°C (1500°F). These washers possess fine thermal stability, superior scaling resistance, and high mechanical strength, providing dependable performance under challenging conditions. They can retain their structural integrity and durability in challenging environments due to their special alloy composition, making Stainless Steel 446 Washers the best fastening option for long-term performance in high-temperature and corrosive environments.
Stainless Steel 446 Washers are widely used in applications where high-temperature and oxidation resistance are essential. They are commonly used in automotive exhaust components, aerospace parts, petrochemical facilities, and incinerators. They are crucial in locking bolted joints, avoiding leaks, and guaranteeing operational performance under heat and corrosive exposure.
