Long-standing expertise in Shot Peening Media

Enhanced Component Life

Shot peen is used in blasting operations. It is a cold working process in which the surface of a workpiece is bombarded with small spherical particles to remove residual tensile stresses and/or add compressive stresses to the workpiece.  

As a result, the use of shot peen increases the life of many components by eliminating residual tensile stress and resisting applied tensile stress.

Nature of shot peen media

Media offerings

Shot peening is highly advantageous when:  

– shot peening induces a large magnitude localized compressive stress to compensate for the stress concentration factor created by these geometric changes.  

– compressive stress is directly correlated to the tensile strength of the material, the higher the tensile stress, the more compressive stress can be induced. 

Hard/high strength metals tend to be more brittle and susceptible to notching. These conditions can be overcome by shot peen, allowing these metals to be used under fatigue conditions.  

Among others, these are the most common treated materials by shot peening: 

  • Carburized steels  
  • Decarburized steels  
  • Austempered Ductile Iron  
  • Cast Iron  
  • Aluminum Alloys  
  • Titanium  
  • Magnesium

Peen forming :

  • The preferred method of forming aerodynamic contour into aircraft wing skins. Residual compressive stress acts to elastically stretch the peened side. Coverage is not a critical parameter.

Contour correction:

  • t can be used to correct unfavorable geometry conditions. This is achieved by shot peening selective locations of the parts. Examples of contour correction are: Driveshaft/crankshafts straightening / Roundness correction of ring shaped geometries / Welding distortion correction / Aircraft wing stiffener adjustment
