Summary:

The peening of fine steel beads with diameters less than 80 micrometers onto the surface of a spring (referred to as SS Treatment in this paper) was found to improve the fatigue limit of the spring effectively since the surface compressive residual stress and surface hardness were improved significantly. As an example, by applying this technology to nonnitrided highstrength valve springs made from the socalled highstrength oil tempered wire, the fatigue limit was increased to the nearly equivalent level as the nitrided and conventionally shotpeened valve springs made from the same highstrength wire. This means that the SS Treatment can be used as a substitute to the nitriding process which has been applied in order to get improved fatigue property of highstrength valve springs
