Incoloy 800H/NS112A/UNS N08810 High-Temperature Alloy Bolt For High-Temperature Applications With Global Standard
The Incoloy 800H (NS112A / UNS N08810 / 1.4876) bolt is a high-performance fastener designed for extreme environments, particularly in high-temperature and corrosive applications. Made from a nickel-iron-chromium alloy, it offers excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures, typically up to 1100°C (2012°F). The alloy’s enhanced creep and rupture strength is achieved through controlled carbon and grain size optimization.
Commonly used in heat exchangers, power plants, furnace components, and petrochemical processing, these bolts maintain superior mechanical properties under thermal cycling and stress. They also resist chloride-induced stress corrosion cracking, making them ideal for offshore and chemical industries.
