Home > Stainless Steel 304H Nuts
Majid Fasteners stands out as a top manufacturer and supplier of Stainless Steel 304H Nuts in Dubai, UAE. They specialize in providing industrial-grade fastening solutions that are built to last, ensuring superior durability and performance. Thanks to their state-of-the-art manufacturing facilities and rigorous quality control processes, the company guarantees products that not only meet international standards but also deliver exceptional strength and corrosion resistance.
The composition of Stainless Steel 304H Nuts includes 18–20% Chromium, 8–10.5% Nickel, up to 2% Manganese, 0.75% Silicon, and 0.04–0.10% Carbon, along with trace amounts of Phosphorus and Sulfur. The higher carbon content boosts their strength at elevated temperatures and enhances mechanical stability. These nuts boast a minimum tensile strength of around 515 MPa and a yield strength close to 205 MPa, all while maintaining excellent ductility and toughness. They can withstand high temperatures of up to approximately 870°C and show remarkable resistance to oxidation and corrosion, making them perfect for critical engineering applications.
