Abstract This paper describes the influence of the shot size, the shot velocity and the workpiece hardness on the characteristics of peened surfaces and surface layers. In order to clarify the clear influences of those factors, medium carbon steel (S45C) was peened by a centrifugal type peening machine using 4 different cast steel shots. Following results are obtained; (1) The diameter of dent is in proportion to the shot size and the square root of the shot velocity, and in inverse proportion to the fourth root of the workpiece
