Stainless Steel 384 Nuts are made from a high-strength austenitic stainless steel alloy containing chromium, nickel, and molybdenum. This composition ensures excellent corrosion resistance, toughness, and mechanical stability. Typical tensile strength ranges from 650–850 MPa, with hardness around 200–240 HB, providing wear resistance and dimensional reliability. The austenitic structure allows these nuts to maintain performance under mechanical stress and exposure to harsh or corrosive environments. 384 Nuts are engineered to offer dependable fastening performance in critical industrial, mechanical, and structural applications requiring long-term durability.
