Khaleed Stainless stands out as a top manufacturer and supplier of Stainless Steel 347H Stud Bolts in Riyadh, Saudi Arabia, delivering high-quality fastening solutions for industries with tough demands. The 347H grade is a high-carbon austenitic stainless steel that’s stabilized with niobium, giving it exceptional resistance to intergranular corrosion, especially at high temperatures. These stud bolts are celebrated for their impressive mechanical strength, creep resistance, and their ability to handle high-pressure and high-temperature situations. Thanks to their durability and reliability, 347H stud bolts find extensive use in chemical processing, power generation, and refinery applications.
Stainless Steel 347H Stud Bolts are mainly made up of chromium (17–19%), nickel (9–13%), and carbon (0.04–0.10%), along with some niobium, manganese, silicon, phosphorus, and sulfur. This well-balanced composition guarantees excellent oxidation resistance and stability even at elevated temperatures. In terms of mechanical properties, they boast a tensile strength of around 515 MPa, a yield strength of about 205 MPa, and an elongation of 35%. The higher carbon content in 347H boosts its creep strength, making it perfect for prolonged exposure to heat and pressure.
