3.Introduction:
GCr15 steel is the representative of high carbon chromium bearing steel with good comprehensive properties. After quenching and tempering, the hardness is high and uniform, and the wear resistance and contact fatigue strength are high. Good hot workability. The spheroidizing annealing has good machinability, but it is sensitive to the formation of white spots. It is mainly used for manufacturing steel balls, rollers and shaft sleeves on transmission shafts of internal combustion engines, electric locomotives, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles and mining machinery.
