ABOUT ALLOY 800 / INCOLOY 800

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. Incoloy 800 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).
