N08811/Incoloy800HT/NS112B High-Temperature Alloy Bolts Withstand Extreme Environments
The N08811 (Incoloy 800HT, NS112B) bolt is a high-performance fastener designed for extreme environments requiring superior heat and corrosion resistance. Made from nickel-iron-chromium alloy, it excels in high-temperature applications up to 1100°C (2012°F) while maintaining structural integrity and oxidation resistance.
This alloy offers enhanced creep and stress rupture strength, making it ideal for use in heat exchangers, furnace components, petrochemical processing, and power plants. It resists carburization, sulfidation, and chloride stress corrosion cracking, ensuring durability in aggressive conditions.
Compliant with ASTM B408 and ASME SB408 standards, N08811 bolts provide excellent mechanical stability and prolonged service life. Their combination of high strength, thermal stability, and oxidation resistance makes them a reliable choice for demanding industries such as aerospace, chemical processing, and nuclear power.
When selecting Incoloy 800HT bolts, consider factors like operating temperature, environment, and mechanical load to ensure optimal performance and longevity.
