The wheel is a kind of classification of forging, mainly used in the portal crane - port machine - bridge crane - mining machine, etc. The wheels of the wheels, the wheels of the Hong Kong machine, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels, the wheels

Common wheel forgings: 60 #, 65Mn, 42CrMo

The wheel is a more vulnerable part. According to the requirements of the vehicle using characteristics of wheel tread has higher hardness, and there is a certain depth of hardening layer and transition layer (> 10 mm in depth, hardness HRC40 a 48), in order to improve the bearing capacity, wear resistance and contact fatigue resistance performance. At the same time, the matrix organization are required to have good comprehensive mechanical properties and good organization state, the hardness should be HBS187 ~ 229, high toughness, improve the shock resistance and cracking resistance.
