Abstract This paper examines the effect of mean stress on fatigue behavior very hard carburized steels. Current theories suggest that maximum at limit continuously decreases with decreasing minimum whereas results this study indicate remains constant for stresses less than fully reversed amplitude stress. The theory proposed by authors corrects error maintaining in compressive region.
