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.
