Stainless Steel 442 nuts are made from ferritic stainless steel, primarily consisting of iron and chromium, with chromium levels between 18–23%. This alloy is known for its excellent resistance to oxidation, scaling, and corrosion, even at high temperatures. They boast impressive mechanical properties, including tensile strength, creep resistance, and thermal stability. Thanks to their ferritic structure, these nuts have magnetic properties and are less susceptible to stress corrosion cracking. Stainless Steel 442 nuts are appreciated for their ability to maintain dimensional stability, toughness, and reliable fastening performance in high-temperature and corrosive environments.
