Incoloy 800 is a widely used nickel-iron-chromium alloy that offers superior strength and resistance to high temperatures and corrosion. It is an ideal material for use in various industrial applications such as chemical processing, heat treating, petrochemicals, power generation, and more. In this article, we will explore the properties, composition, standards, and applications of Incoloy 800 in depth.
Introduction to Incoloy 800
Incoloy 800, also known as UNS N08800, is an alloy of nickel-iron-chromium with added titanium, aluminum, and carbon. It exhibits good strength and excellent resistance to oxidation, carburization, and nitriding at elevated temperatures. Its high-temperature strength is due to the solid solution strengthening effect of the nickel and chromium and the precipitation hardening effect of the titanium and aluminum.
The nominal chemical composition of Incoloy 800 is 39.5% nickel, 30% iron, 19% chromium, 0.15% carbon, 0.15% titanium, and 1% aluminum. The alloy can be easily formed, machined, and welded using standard techniques. It is available in different forms such as pipe, plate, strip, round bar, and wire.
