A temperature of the wheel rim/the spoke blank being required to be kept above a required temperature in a process of transferring the heated wheel rim/the heated spoke blank to the hot press. Then the wheel rim/the spoke blank is formed in the hot press. A formed wheel rim (102) and a formed spoke (104) are connected to product a steel wheel (100). A wheel formed by hot stamping and a manufacturing method are provided. Not only are weight smaller than that of a steel wheel produced by a conventional method, higher effectiveness and lower cost achieved, but also dimensional stability and durability of a product may be ensured. The technical problems in the conventional art that a heat treatment method is time-consuming and high in cost and a produced wheel is easy to fail are solved.
