● Hardness of grinding steel ball. General speaking, The better wear resistance, the higher hardness.
● Production technology of grinding steel ball. The more dense of grinding steel ball and the finer of the crystals, the better wear resistance.
● Carbide. The more carbide, the better wear resistance.
● Heat treatment technology. The wear resistance of grinding steel ball can be best developed only when the hardness value and impact value match well.
