70mm Chrome Steel Bearing Ball For Machine Part 12mm Ball Bearing Balls
GCr15 bearing steel is a high carbon chromium bearing steel with less alloy content,
good performance and the most widely used. After quenching and tempering,
it has high and uniform hardness, good wear resistance and high contact fatigue performance.
The steel has the characteristics of medium plasticity, low cutting performance, poor welding performance,
large sensitivity to white spot and temper brittleness
