Casting Steel Ball
Introduction
It has the advantages of high quality, good impact resistance, good toughness, excellent wear- resistance and it is not easily broken.
Features
1. Breaking rate is lower than 0.5%. Breaking resistance is 10 times than ordinary grinding ball.
2. High impact toughness：Impact toughness is more than 18J/cm2, 8 m falling ball experiments are more than 20000 times.
3. High hardness：Surface hardness 58-67HRC, volume hardness 58-67HRC, hardness gradient is evenly distributed.
4. No deformation.
5. Dense structure，cost-effective.
