Incoloy alloy 800 is a widely used material of construction for equipment that must have high strength and resist carburization,oxidation and other harmful effects of high-temperature exposure. (For high temperature applications requiring optimum rupture and creep properties, Incoloy alloys 800H and 800HT are used). The chromium in the alloy imparts resistance to oxidation and corrosion. The high percentage of nickel maintains an austenitic structure so that the alloy is ductile. the nickel content also contributes general corrosion, resistance to scaling and stress-corrosion cracking. 
Incoloy alloy 800 is used in a variety of applications involving exposure to high temperatures and corrosive environments. It is used for heat-treating equipment such as baskets, trays and fixtures. In chemical and petrochemical processing the alloy is used for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. In nuclear power plants, it is used for steam-generator tubing. The alloy is often used in home appliances for sheathing of electric heating elements. In the production of paper pulp, digester liquid heaters are often made of alloy 800. In petroleum processing , the alloy is used for heat exchangers that air-cool the process stream.
Incoloy 800 is a nickel-chromium alloy with good strength and excellent resistance to oxidation and carburization. The alloy maintains stable structure during exposure to high temperature, therefore incoloy 800 has good  corrosion resistance  to many acidic environments.


Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800AT (UNS N08811) are nickeliron-chromium alloys designed to resist oxidation and carburization at elevated temperatures through 1900 °F. The nickel content, 32 %, makes the alloys highly resistant both to 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 800AT have superior creep and stress rupture properties. All three versions of the basic Alloy 800 have been approved as materials of construction under ASME Boiler and Pressure Valve Code, Section I-Power Boilers, Section III-Nuclear Vessels, and Section VIII-Unfired Pressure Vessels. Alloys 800, Alloy 800H and Alloy 800AT are identical except for the higher level of carbon (0.05 to 0.1 %) in Alloy 800H, and the addition of up to 1 % aluminum + titanium in Alloy 800AT. The Alloy 800 is normally used in this service at temperatures to approximately 1100 °F (593 °C). Alloy 800H and Alloy 800AT are normally used above approximately 1100 °F (593 °C) where resistance to creep and rupture is required.
