Incoloy800 (UNSNO8800/W. Nr. 1.4876) is a structural material widely used for equipment requiring corrosion resistance, heat resistance, high strength and stable service up to 1500 ° F (816 ° C). Incoloy800 is resistant to uniform corrosion and stress corrosion cracking in many aqueous solutions due to its nickel content. At higher temperatures, it provides resistance to oxidation, carburization and vulcanization, and has certain cracking and creep strength. For applications requiring higher cracking resistance and creep, especially when the temperature is higher than 1500 ° F (816 ° C), INCOLOY800H and 800HT shall be used. Chromium in Incoloy800 provides both water solution and heat resistance. Iron provides internal oxidation resistance. Nickel content maintains ductility and austenite structure. So Incoloy800 can be used for forming, welding and machining.

Incoloy800 is used in various environments involving corrosion and high temperature. It is used for heat treatment equipment such as baskets, pallets, clamps, etc. This alloy is used as nitric acid medium in chemical and petrochemical processes, especially for heat exchangers and other piping systems that require resistance to chloride ion stress corrosion. They are used as steam generator tubes in nuclear power plants. This alloy is usually used for the shell of electric heating elements in household appliances. In pulp production, the heater for cooking solution is often manufactured by Incoloy800. In the petroleum industry, the alloy is used to manufacture heat exchangers for air cooling process steam.
