high chrome cast iron heat treatment

Heat treatment process of the high chrome cast iron

The microstructure of high chromium white cast iron grinding ball as-cast and after heat treatment was observed by metallographic microscope. The sample of 10mm* 10 mm* 8 mm in size at the center of the grinding ball was cut by weld and polished with 200 # to 1500 # metallographic sandpaper.

Study on the heat treatment process of high chrome cast

When the cooling rate is high, high chromium cast iron’s impact toughness worsens after quenching, and the hardness increases. So it’s very important to do the heat treatment. Therefore, in the actual production, the general use of cooling strength is weak air cooling to avoid casting in order to prevent serious consequences.
