Heat Treatment Technology of High Chromium Iron

2020-10-2  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.
