What is Shot Peening
Shot peening is a process used to produce a compressive residual stress layer of metal on parts such as gears, cams and camshafts, clutch springs, coil springs, connecting rods, crankshafts, gearwheels, and turbine blades. Similar to abrasive blasting, shot peening operates on the principle of plasticity rather than abrasion: each particle functions as a ball-peen hammers, changing the mechanical properties of the surface, relieving tensile stress, and replacing it with beneficial compressive stress.
Why Use Shot Peening
When first discovered in the late 1920s, shot peening was used by the automotive industry to increase the life of valve springs. Today, it has many useful applications across a handful of industries. In addition to increasing the residual strength of a part, shot peening can provide and enhance surface finish. Studies have shown that parts, after peening, have a greater life span over non-peened parts.
