WebHere’s a brief overview of the more common types of inclusions: 1. Alumina (Al 2O 3) is found in steel in which aluminum has been added typically to control grain size or as a deoxidant. It can also be carried into steels from refractories in which case the inclusions tend to be large and isolated.
