Stainless steel nuts are typically made from grades like 304, which contains 18% chromium and 8% nickel, or 316, which adds 2-3% molybdenum for better corrosion resistance. They have tensile strengths ranging from 500 to 750 MPa and show great resistance to rust, oxidation, and acids. These nuts maintain high ductility, toughness, and fatigue resistance, even in high temperatures. The 316 grade is particularly effective in marine or chloride-rich environments. Their mechanical properties make stainless steel nuts ideal for load-bearing, vibration-resistant, and high-pressure applications where long-lasting performance is essential.
