N08811/Incoloy800HT/NS112B High-Temperature Alloy Bar for Thermal Processing Equipment


The N08811 (Incoloy 800HT/NS112B) high-temperature alloy bar is a nickel-iron-chromium alloy designed for excellent strength and oxidation resistance in high-temperature environments. It has enhanced creep and rupture strength due to controlled carbon, aluminum, and titanium content. The alloy resists oxidation, carburization, and sulfidation, making it ideal for applications in heat exchangers, furnace components, petrochemical processing, and power generation. It maintains structural stability up to 1100°C (2012°F), ensuring reliability in extreme conditions. With good weldability and corrosion resistance, N08811 is widely used in industries requiring superior thermal stability and mechanical strength. Its high nickel content also improves resistance to chloride stress corrosion cracking, enhancing durability in harsh environments.
