In centrifugal casting, the outer surface is typically smoother than the inner surface due to the centrifugal force exerted during the process, which pushes impurities towards the inner surface. The outer surface also tends to have a finer grain structure compared to the inner surface. The inner surface may exhibit greater porosity and can be more susceptible to defects due to the cooling process occurring more rapidly on this surface.
