  • Method for the production of a part of a rolling bearing
    Patent number: 6837946
    Abstract: Method for the production of a part of a rolling bearing, such as a ring for a ball bearing. The starting material used is a grade of steel containing 0.90 1.00% C; at most 0.15% Si; 0.25-0.45% Mn; at most 0.0015% P; at most 0.010% S; 1.30-1.50% Cr; at most 0.15% Ni; 0.20-0.23% Mo; at most 0.20-0.23% Cu; at most 20 ppm Ti; at most 8 ppm O. Before subjecting this grade of steel to a quenching and tempering treatment, the shaped item is subjected to plastic deformation in the hot or cold state. The mechanical properties and in particular the anticipated life under severe stress improve as a result.
