Shot Peening increases resistance to: Fatigue failure, Corrosion fatigue, Hydrogen assisted cracking, Cavitation erosion, Stress corrosion cracking, Galling Fretting.

  Shot Peening Helps with: surface texturing, intergranular corrosion resistance, closing of porosity, testing of bond coatings, work hardening, increased strength, and increased durability.

It is a method of cold working in which compressive stresses are induced in the exposed surface layers of metallic parts by the impingement of a stream of shots directed at a metal surface at high velocity under controlled conditions.
