Categories By Function
Incoloy alloy is also a range of superalloys produced by Special Metals Corporation. They are nickel-iron-chromium alloys that are used for applications which require high corrosion resistant and high temperature strength. Incoloy alloys are quite similar to Inconel alloys but their different composition makes some distinctions in their applications.
Alloy 800 is a widely used material of construction for equipment that must resist corrosion, have high strength or resist oxidation, carburization and other harmful effects of high-temperature exposure. The Chromium in the alloy imparts resistance to oxidation and corrosion. The high Nickel content maintains an austenitic structure so that the alloy is ductile. The Nickel also contributes resistance to scaling, general corrosion and stress corrosion cracking. The iron content provides resistance to internal oxidation.

Chemical Composition, %
Applications of Incoloy 800:
- Steam / hydrocarbon reforming for components such as pig tails, headers, collectors, manifolds, transfer piping, catalyst tubes, and quench system piping
- Ethylene pyrolsis tubing in convection and radiant sections - resistance to carburization and good mechanical properties
- Ethylene dichloride cracking tubes - resistance to carburization and to dry hydrogen chloride and chlorine components, e.g. Heat exchangers, piping systems, etc., in coal conversion plants
- Steam generators tubing in helium coolant, high temperature reactor systems - high strength, resistance to helium and steam
