Feature: 

Belong to a kind of high carbon chromium bearing steel which most widely used width a good performance and less alloy content. High hardnability and good comprehensive performance. Good machinability after spheroidizing annealing. High hardness, uniformorganization, good wear-resistance, high contact fatigue performance after quenching and tempering. And good hot working performance.
