Stainless Steel 442 Nuts are composed mainly of iron, chromium (18–23%), and molybdenum, which together enhance their resistance to oxidation, scaling, and corrosion at elevated temperatures. They possess a ferritic structure that provides good strength and toughness while maintaining stability under thermal stress. Mechanically, these nuts exhibit high tensile strength, excellent creep resistance, and good hardness. Their low thermal expansion and good ductility make them ideal for use in environments exposed to both high heat and mechanical stress, ensuring secure and long-lasting connections.
