UNS Number NO8800 / N08810 / N08811

Other common names: Alloy 800, Alloy 800H, Alloy 800HT

Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 percent aluminum and titanium in alloy 800HT. Incoloy 800 was the first of these alloys and it was slightly modified into Incoloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. Incoloy 800HT has further modifications to the combined titanium and aluminum levels (.85-1.20%) to ensure optimum high temperature properties.The nickel alloy is dual certified (800H/HT) and combines the properties of both forms. Incoloy 800H/HT alloy was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties. Today, most suppliers, including Prosaic Steel, only carry the dual certified 800H/HT alloy.

Incoloy 800 is primarily used in applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. Incoloy 800HT will not become embrittled even after long periods of usage in the 1200-1600° F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with 800HT. When cold formed extensively the grain size produces a visibly undulated surface called "orange peel”. Incoloy 800HT can be welded by the common techniques used on stainless steels.

Inconel 800 or Incoloy 800, or perhaps even 800H or 800HT. Inconel 800 goes by many names and carries with it a few variations. Incoloy 800 originally developed by Special Metals has been around since the 1950s but back then, Nickel wasn't as widely available and really only used for special cases when producing certain steels. This grade has always been known to contain properties for high temp strength and resistance to carburization, oxidation and other high temp corrosion.

The variations of this grade come in 2 forms, Incoloy 800H and Incoloy 800HT. The 800 variety has a higher level of Carbon than the straight 800 counterpart which allows for a higher creep. Incoloy 800 HT features a restricted elemental structure that is within standard 800H chemistry but also requires heat treating. The variation of the Carbon, Aluminum and Titanium give the 3 grades of 800, 800H and 800 HT similar properties but not 100% the same, thus the need to split out this group into 3 alloys.

Incoloy refers to a range of superalloys produced by the Special Metals Corporation group of companies. They are mostly nickel-based, and designed for excellent corrosion resistance as well as strength at high temperatures; there are specific alloys for resistance to particular chemical attacks (e.g. alloy 020 is designed to be resistant to sulphuric acid, DS to be used in heat-treating furnaces with reactive atmospheres and many heat cycles)

Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternatives to the various Incoloy brand alloys.The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical and petrochemical processing, power plants, and oil and gas industries widely use these superalloys.
