Stainless Steel 446 nuts are made from ferritic stainless steel, featuring a high chromium content that typically falls between 24% and 27%. This unique composition grants them remarkable resistance to oxidation, scaling, and sulfidation, even when exposed to high temperatures. They boast impressive tensile strength, hardness, and creep resistance, ensuring they maintain their structural integrity in extreme thermal conditions. Thanks to their ferritic structure, these nuts also exhibit magnetic properties and are built to withstand thermal fatigue and chemical exposure. With reliable dimensional stability and consistent mechanical performance, Stainless Steel 446 nuts are perfectly suited for high-temperature and corrosive environments.
