Shot peening is a method of cold working a part surface under a spray or blast of round shot to increase a part's fatigue life. Fatigue failures usually begin on the surface of a part. Shot peening makes tiny dents or curves on the surface of the metal. This creates a layer of compressive stress, which delays the creation and growth of fatigue cracks. In some instances, peening can increase the fatigue life of a part by 2,000% or more.
