Does shot peening increase hardness?

Shot peening is when the spherical abrasive is tossed at high speed over a metallic surface of machine components to remove its impurities. The impact of the granules on the metal changes the surface.

During the shot peening process, the metal is compacted due to the granule pressure, which offsets the compressive stress acting over the part. The equipment crack risk by stress ends up being reduced.

According to some studies, shot peening can increase component life in service by up to 1,300%. Reduced tensile stress on the surface can reduce equipment fatigue by 560%. The components that can improve service life are gearboxes, crankshafts, blast wheel blades, or other blast wheel components.
