Khaleed Stainless is a reliable manufacturer and supplier of top-notch Stainless Steel 304H Nuts based in Riyadh, Saudi Arabia. We provide dependable fastening solutions designed for high-temperature and high-pressure industrial applications. SS 304H is a high-carbon austenitic stainless steel known for its impressive tensile strength, outstanding corrosion resistance, and remarkable durability even in extreme conditions. Our nuts are precision-engineered to comply with international standards and come in a variety of sizes, grades, and thread types. Perfect for industries like petrochemical, power generation, chemical, and marine, these nuts guarantee secure, leak-proof connections and long-lasting performance in demanding environments where safety and reliability are paramount.
Stainless Steel 304H Nuts are composed of 18–20% chromium, 8–11% nickel, and 0.04–0.10% carbon, which boosts strength at high temperatures and enhances creep resistance. They also contain ≤2% manganese, ≤1% silicon, and trace amounts of phosphorus and sulfur. With a tensile strength of around 515 MPa, yield strength of 205 MPa, elongation of 40%, and a Brinell hardness of about 201 HB, these nuts offer exceptional mechanical stability. The high-carbon content contributes to their durability, while the austenitic structure ensures corrosion resistance, weldability, and toughness, making them ideal for high-stress industrial and structural applications.
