The invention provides a high-strength heat-resistant hub and a preparation process thereof. According to the preparation technology of the hub, the raw materials are prepared according to the target alloy composition, then smelting, melt purification, casting, homogenizing annealing treatment, hub die forging precision die forging forming, solid solution quenching and artificial aging are conducted, and the hub is obtained by optimizing the alloy composition, controlling the conditions of all the procedures and the like. The inner side hub die forging product and the outer side hub die forging product are successfully manufactured, and the performance of the inner side hub and the performance of the outer side hub are improved. Test results show that various detections (room-temperature tensile property, high-temperature tensile property, low magnification, high magnification, hardness, flaw detection, surface quality and the like) of the inner side hub and the outer side hub all meet the technical index requirements.
