Abstract: Surface hardness, magnetic properties and residual stress of stainless steel were analyzed from the shot peening strengthening method, and the influence of shot peening parameters on stainless steel materials was reviewed, the mechanism of shot peening is revealed, and the effect of shot peening on the residual stress in stainless steel was analyzed. The relationships between material properties and hardness, and the effects of shot peening time and shot size on the surface properties of stainless steel are introduced in detail, and the development direction of shot peening on stainless steel surfaces treatment is prospected.

Key words: shot peening, hardness, microstructure, residual stress
