Shot Peening

Virtual Scientific Industries is the first company fully dedicated to exclusively offer complete Shot Peening services in the Kingdom of Saudi Arabia and GCC. Shot Peening is a cold working process that imparts compressive stresses and relieves Residual tensile stresses to improve the fatigue life of metallic components, imparts anti-galling properties, creates a specific surface profile and improves resistance to stress corrosion cracking.

Shot Peening is the cold working process accomplished by pelting the surface of metal part with the spherical media, thrown relatively at high velocity. This imparts the compressive residual stresses and relives the tensile residual stresses to improve fatigue life of the component.

Why Shot Peening is Important?

Shot peening has improves metal fatigue properties and extend the life of critical components and reduce the premature failure. Metal fatigue occurs when cyclic loading and the associated tensile stress cause a crack to start in a highly stressed area. Shot peening is able to mitigate this by imparting a high magnitude, residual compressive stress at the surface in the potential failure area.

Compressive residual stresses induced by the shot peening prevent initiation of crack induced by tensile stresses. Parts that have been shot peened are able to survive many times longer due to the surface being placed in a residual compressive state.

How Shot Peening Works?

Each piece of shot hits the surface and creates an indentation in form of a dimple. This creates a beneficial compressive residual stress which makes the surface resistant to crack initiation and propagation. Post manufacturing tensile stresses are converted to residual compressive stress.

Beneficial Compressive Residual Layer

The residual stress generated by shot peening is of a compressive nature. This compressive stress offsets or lowers applied tensile stress.
