Heat Treatment Technology of High Chromium Iron Castings

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. Heat treatment is almost a necessary process for every high chromium iron casting. Reasonable quenching can make the casting obtain the best ability to resist abrasive wear.
