High Temperature Alloy Bar UNS N08800/Incoloy800/NS111/1.4558/X2NiCrAlTi3220/NCF800/NCF2B For Industrial Applications
The UNS N08800 (Incoloy 800) alloy bar is a high-temperature, corrosion-resistant nickel-iron-chromium alloy designed for use in extreme environments. Also known as NS11, 1.4558, X2NiCrAlTi3220, NCF800, and NCF2B, this alloy offers excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. Its balanced composition ensures high mechanical strength and structural stability, making it ideal for applications in heat exchangers, furnace components, chemical processing, and power plants.
With good resistance to stress corrosion cracking and aqueous corrosion, Incoloy 800 performs well in high-temperature and pressure conditions. The addition of aluminum and titanium enhances its creep and rupture strength, ensuring long-term durability. It is commonly used in petrochemical processing, nuclear power plants, and aerospace applications. Available in bar form, Incoloy 800 is easy to fabricate, weld, and machine, making it a preferred choice for demanding industrial applications requiring strength, thermal stability, and corrosion resistance.
