Factory HOT ROLLED ASTM 52100 bearing steels bar steel round bar Price per ton

Have good comprehensive performance.  have the high and uniform hardness after quenched and tempered. Have  good performance in cutting and processing after spheroid annealing.

GCr15 bearing steel is the most widely used high carbon chromium bearing steel with low alloy content and good performance. After quenching and tempering, it has high uniform hardness, good wear resistance and high contact fatigue performance. The cold working plasticity of the steel is medium, the cutting performance is general, the welding performance is poor, to form a white point sensitive performance, has the temper brittleness.

Application:

1) Steel ball, roller and collar of large machinery bearing

2) High-hardness and high contact fatigue strength machinery parts with heavy load, such as axis of rotation, blade, stator pump, profiling, sleeve, mandril, etc.

Comparable Standards:
