Emilio Stainless, located in Manila, Philippines, is a reliable manufacturer and supplier of top-notch Stainless Steel 304H Stud Bolts. These bolts are specifically designed for high-temperature and demanding industrial settings, offering outstanding corrosion resistance, mechanical strength, and long-lasting durability. The 304H grade, which has a higher carbon content than the standard 304, delivers enhanced tensile strength and heat resistance, making them perfect for high-pressure and high-temperature piping systems. At Emilio Stainless, each stud bolt undergoes precision manufacturing and rigorous quality control, ensuring secure, leak-proof, and dependable fastening solutions for various applications, including chemical, petrochemical, power generation, and industrial sectors.
Stainless Steel 304H Stud Bolts are made up of 18–20% chromium, 8–10.5% nickel, and a carbon content ranging from 0.04–0.10%, along with small amounts of manganese, silicon, and phosphorus. These austenitic stainless steel bolts boast a tensile strength of 520–620 MPa and a yield strength of about 210–310 MPa, along with excellent ductility and toughness. The increased carbon content improves high-temperature strength while maintaining resistance to corrosion and oxidation. 304H stud bolts ensure dimensional stability and mechanical integrity under stress, making them well-suited for high-temperature and high-pressure industrial and engineering applications.
