These stud bolts are crafted using cutting-edge production methods and rigorous quality control measures, ensuring they have precise threading, consistent dimensions, and dependable mechanical strength. Mazin Fasteners caters to various industries, including petrochemical, chemical processing, power generation, and marine engineering. Renowned for their durability, thermal stability, and resistance to intergranular corrosion, these stud bolts are perfect for critical applications that demand secure and long-lasting fastening in extreme heat and harsh environments.
The Stainless Steel 347H Stud Bolts are made from a stabilized austenitic stainless steel alloy, which contains about 17–19% chromium, 9–13% nickel, and niobium to help prevent intergranular corrosion. With a higher carbon content than 347, they offer enhanced strength at high temperatures. In terms of mechanics, SS 347H stud bolts deliver impressive tensile and yield strength, outstanding hardness, and stability in both thermal and mechanical stress. They resist deformation, fatigue, and scaling, ensuring reliable performance even in prolonged high-temperature conditions.
