Shot Peening: An Introduction MetFin

Shot Peening: An Introduction Shotpeening is a cold working process used to improve the characteristics of metal parts. The basic premise is that small, round media are directed at a part to create dimples on the surface which puts the outer layer of the metal into compression and effectively prevents fatigue failure and stress corrosion cracking.
