A gear part and method is provided for forming a gear part, in which a circular blank-like workpiece is fixed in a flow-forming machine in a radially inner area, the circular blank-like workpiece is rotated, at least one roller is infed and the roller is substantially radially moved inwardly, in which during the radial moving in workplace material flows radially, so that the workplace wall thickness is reduced in this area, in a central area of the workplace a boss is formed and during radial moving in the roller is increasingly axially infed. The method also relates to forming a gear part in which the circular blank edge is thickened by at least one forming roller, the shaping of the circular blank edge taking place through the contour of gripping jaws and/or the forming roller and the cross-section of the circular blank edge in formed in an approximately rectangular manner.
