Actually shot peening and case hardening have very little in common. Shot
peening is just a means of removing surface defects from the material. It
does not make it harder in any way like heat treating or case hardening
does. The purpose of shot peening is to remove the potential starting place
for a fracture. Fractures propigate from the weakest place in the surface
so if the surface is made uniform the chance of a fatigue fracture is
lessened.
