Incoloy800H/NS112A/UNS N08810/1.4876 High-Temperature Alloy Nut For Oxidation Carburization and Sulfidation Resistance

Incoloy 800H is a high-temperature, corrosion-resistant alloy primarily composed of nickel, iron, and chromium. It is an advanced version of Incoloy 800, with controlled carbon content (0.05–0.10%) and grain size optimization for enhanced creep and rupture strength. This alloy offers excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures up to 1100°C (2012°F). It is widely used in heat exchangers, furnace components, petrochemical processing, and power generation applications.

NS112A, UNS N08810, and 1.4876 are equivalent designations, ensuring global standard compliance. Incoloy 800H bars are available in various diameters and lengths, with good weldability and formability. Their mechanical stability and resistance to high-temperature corrosion make them ideal for demanding environments.
