Shot peening basics

The shot peening process is used to enhance the properties of springs for high performance applications. It consists of impacting a metal surface with media (known as a shot). The shots used are typically round metallic, glass or ceramic particles, which act like a tiny ball-peen hammer as they are blasted at a surface. The process creates a uniform layer of compressive stressed metal.

The result of this process is increased part life. Afterwards, the metal surface is more resistant to fatigue and stress corrosion failures.


The shot peening process is typically performed on parts that will have to withstand multiple shocks and heat. Some common applications include engine valve springs, coil springs, leaf and suspension springs, and high-performance die springs. 

Shot peening is also used in the aerospace industry during aircraft repair to relieve stress from grinding and increase fatigue life. In addition, the process is sometimes used for cosmetic purposes. The overlapping dimples created by shot peening result in a more pronounced light scattering effect than sand blasting.

No matter the application, Springs & Things has the expertise to help, as the company’s senior sales and production staff has a total of 125 years of experience in spring manufacturing.
