- High hardness, and hardness gradient uniform distribution.
the gap between core and surface hardness within 2~5HRC, which guarantee the balls with good roundness. - Low breakage rate, according to the industry standard in our country, the breakage rate of ball is less than 0.3%.
- Good mechanical properties, in processing, the balls quenched in water, subsequent tempering. Keep the ball under 180~220 celcius, make the ball have good impact properties. The mechanical properties of steel balls have good impact to the mill liners and ball mills.
- Chemical composition, the raw materials of our products are alloy steel bars which the chemical composition is stable and accurate.
- Overall quality control, we built our own quality inspection center.
- Environmental, In processing, treatment by gas, low energy consumption, and no pollution.
