ABSTRACT:
Steel elements designed to withstand high stress, such as roller bearing elements, are produced by using a steel which has substantially eutectoid composition, a such a steel billet being plasticly formed, without prior soft-annealing, at a temperature just above the A1 temperature of the steel, to a shape approaching the final shape of the element, the element thus shaped being thereafter hardened directly from the forming temperature and being subsequently subjected in conventional manner to final grinding and polishing if required.
