Product Description



3mm 4mm 5mm 10mm AISI5200 304 Solid Stainless Steel 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
