With a strong commitment to precision, durability, and adherence to international quality standards, Xuan Nickel Alloys provides products that cater to the rigorous demands of industries around the globe. Their Incoloy 800 series stud bolts are highly regarded for their outstanding performance in sectors like power generation, petrochemicals, marine, and chemical processing, ensuring reliability and a long lifespan even in tough operating conditions.
The Incoloy 800/800H/800HT Stud Bolts are made from a blend of nickel, iron, and chromium, with carefully controlled amounts of carbon and aluminum-titanium. Incoloy 800 is known for its excellent resistance to oxidation and corrosion at elevated temperatures, while the 800H and 800HT variants, which have a higher carbon content and optimized heat treatments, provide improved creep and rupture strength. These alloys boast remarkable mechanical properties, including high tensile strength, ductility, and stability, even during extended high-temperature use. Their ability to resist carburization, sulfidation, and scaling makes them a trustworthy fastening solution for components that face thermal stress and corrosive elements.
