At Nasir Nickel Alloys in Manama, Bahrain, Incoloy 800/800H/800HT Stud Bolts are developed to meet the demanding requirements of high-temperature and high-stress industrial environments. These nickel-iron-chromium alloys are designed to retain strength and resist deformation during prolonged exposure to elevated temperatures. The 800H and 800HT grades provide enhanced creep and rupture resistance, making them ideal for severe thermal conditions. Their remarkable stability against oxidation, carburization, and thermal fatigue ensures reliable fastening even in fluctuating operating environments. Incoloy 800/800H/800HT Stud Bolts offer consistent, long-lasting performance wherever durability and high-temperature integrity are critical.
Incoloy 800/800H/800HT Stud Bolts contain nickel, chromium, and iron as primary elements, along with controlled additions of carbon, titanium, and aluminum. These elements work together to offer strong resistance to oxidation, carburization, and general corrosion at elevated temperatures. The 800H and 800HT grades provide enhanced mechanical strength due to optimized carbon levels and heat treatment. These stud bolts exhibit excellent tensile and yield strength, strong creep resistance, and outstanding thermal stability. Their ability to maintain structural integrity under severe heat exposure makes them ideal for demanding thermal applications.
