Crane wheels (crane wheels, overhead crane wheels, and overhead crane wheels) are relatively easy to damage and wear crane components. According to the usage characteristics of the crane crane, it is required that the wheel tread has high hardness, and there is a certain depth of hardening layer and transition layer (depth>10mm, hardness HRC40-48) to improve the bearing capacity, wear resistance, and contact fatigue resistance. At the same time, it is required that the matrix structure has good comprehensive mechanical properties and a good organizational state, with a hardness of HBS187~229, making it have high toughness, improving impact resistance and cracking resistance.
