INCOLOY alloy 800 is an Iron nickel chromium alloy with a low carbon content with good strength and resistance to oxidation and carburization to intermediate temperatures. The alloy has been used in some steam generation plant due to the resistance to stress cracking however improved materials have tended to supercede

the material for this application. The alloy is a stable austenitic structure which demonstrates good resistance to thermal cycling and finds application in the iris of theatrical spotlights, heater element sheathing, heat exchangers and petrochemical process piping (pigtails).
