UNS N08800/Incoloy800/NS111/1.4558/X2NiCrAlTi3220/NCF800/NCF2B High Temperature Alloy Bolt For Extreme Industrial Settings
The UNS N08800 (Incoloy 800) high-temperature alloy bolt is engineered for extreme heat and corrosive environments. This nickel-iron-chromium alloy offers excellent resistance to oxidation, carburization, and high-temperature corrosion, making it ideal for heat exchangers, furnaces, and power plants. With controlled carbon content and added titanium and aluminum, it maintains strength and stability up to 1100°F (593°C).
Equivalent designations include NS11, 1.4558, X2NiCrAlTi3220, NCF800, and NCF2B. These bolts exhibit high mechanical strength, superior creep resistance, and good weldability, ensuring long service life in demanding conditions. Their robust performance in high-stress environments makes them suitable for petrochemical, aerospace, and nuclear applications.
Due to its excellent metallurgical stability, Incoloy 800 bolts prevent premature failure in high-temperature operations. The alloy's versatility and durability make it a preferred choice for securing components in extreme industrial settings, ensuring safety and reliability under thermal and mechanical stress.
