Abstract:  
Abstract This study is to examine the influence of work hardening and compressive residual stress induced by shot peening on the pitting fatigue strength. Test specimens were prepared so that the surface roughness was made to be identical by grinding after two kinds of shot peening to various carburized steels. As a result, the pitting strength increased with the peening intensity and the surface hardness was increased after tempering at 300
