As an anti-wear material, High Chrome White Iron Castings have not only necessary strength and toughness, but also their hardness is the most important quality index. Some high chromium iron castings can obtain the required hardness in the as-cast state, but most of them need heat treatment to meet the hardness requirements.

High chrome balls, Cr over 10%, need to do this process. For tempering, both low chrome and high chrome balls should do. It is to eliminate the inner, so that ensure the ball's HRC from core to the surface are uniformly and increase its tenacity. There are two heating types for the heat treatment process, electricity and gas type.
