Rotational bending fatigue tests were carried out using SCM420H steel with special focus on the effects of Wide Peening Cleaning (WPC) treatment on fatigue properties. Measurements of residual stress and hardness in surface layer were also performed. It was found that WPC process has a beneficial effect on increasing the fatigue strength. This is because WPC process generates the hardened surface layer with high compressive residual stress.
