INCONEL 800

Incoloy 800H®, Ferrochronin® 800, Nickelvac® 800, Nicrofer® 3220

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.
