摘要： A process is provided for manufacturing balls, especially for ball and socket joints, as well as to a ball element for two-part ball pivots. The microalloyed carbon-manganese steel balls are manufactured by cold extrusion and subsequent grinding. Annealing can thus be completely eliminated, as a result of which a less expensive material can be used. The process makes possible a manufacture of balls especially for two-part ball pivots in a simpler manner and at a lower cost, and the surface finish and the material quality as well as the strength and the wear resistance are at the same time preserved or increased. As a result, the effort needed to manufacture the balls is reduced, and, moreover, the problem of the impact marks often developing on the ball surfaces during tempering is eliminated.
