The strength of our 347H Stud Bolts comes from a specific composition, primarily chromium and nickel, with a crucial addition of niobium. This alloying element makes these bolts exceptionally resistant to corrosion and, importantly, prevents a weakening effect known as “sensitization” when exposed to high temperatures. The result is a fastener with outstanding mechanical properties, including high tensile strength and excellent creep resistance, allowing it to perform reliably under continuous stress and intense heat without losing its integrity.
