Shot Peening

Shot-Peening

What is Shot Peening?

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.

What are the advantages of Shot Peening?

 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.

What are the applications of Shot Peening?

Shot Peening when applied on following components increases its service life

 Pins                             –              400-1900%.

 Shafts                         –               700 %

 Helical springs          –              3500 %

 Gears                          –               30 %

Valves                         –               700 %
