In this paper, the influence of shot peening treatments on the mechanical properties of maraging steel has been investigated with the aim of improving fatigue strength of the steel. The main results obtained are as follows. (1) When high hardness existed in the specimens, its shot peening effect was increased and the surface roughness was reduced. (2) The factors of improvement on fatigue strength with regard to the shot-peened specimens are the compressive residual stress and work-hardening of the steel surface. (3) The fatigue strength of the specimens increased at a value of 50 percent using the shot peening treatment.
