We report results from X-ray synchrotron residual strain investigations of conically shaped 17-4PH stainless steel samples treated to different shot-peen intensities. The residual strains are compared to the as-manufactured condition as well as a sample coldwater quenched. The magnitudes of the induced residual strains in the shot-peened samples are in relation to the peen intensities. Investigations on slices cut from the bulk samples indicate a underlying material thickness dependence.
