Cold Finished Bearing Steel Tube Material GCr15 Seamless Steel Tube For Bearing
1. Introduction
Gcr15 Bearing steel tube is a kind of high carbon chromium bearing steel with low alloy content, good performance and widely used. After quenching and tempering, it has high and uniform hardness, good wear resistance and high contact fatigue property. The steel cold working plasticity is medium, the cutting performance is general, the welding performance is poor, to form the white point sensitive property is big, has the temper brittleness.
2. Chemical Component
C:0.95-1.05 Mn:0.20-0.40
Si:0.15-0.35 S:≤0.020
P:≤0.027 Cr:1.30-1.65
3. Application
Bearings are used for ball bearings, roller bearings and bearing rings.
