N08811/Incoloy800HT/NS112B High-Temperature Alloy Nut With Enhanced Creep And Stress Rupture
The N08811 (Incoloy 800HT / NS112B) high-temperature alloy nut is a corrosion-resistant fastener designed for extreme environments. Made from nickel-iron-chromium alloy, it offers excellent strength, oxidation resistance, and carburization resistance at temperatures up to 1100°C (2012°F). Enhanced with titanium and aluminum, it provides superior structural stability and creep resistance. Commonly used in heat exchangers, power plants, furnace components, and petrochemical processing, it withstands harsh thermal cycling and stress conditions. Its high nickel content ensures resistance to chloride-induced stress corrosion cracking. Ideal for high-pressure and high-temperature fastening, N08811 nuts maintain integrity in aggressive environments, ensuring long-term reliability and safety in critical applications.
