Metal Heat Treatment Guide: What is Shot Peening?

Surface treatment method using shot blasting! The size of the steel balls is approximately 0.05 millimeters to several millimeters!

"Shot peening" is a treatment primarily applied to the surface of steel, aimed at achieving work hardening through plastic deformation, uniform surface stress, and the introduction of residual compressive stress. Specifically, it involves projecting a media (small steel balls mainly referred to as steel shot or steel beads) onto the workpiece by means of air pressure or mechanical force. The speed of the projected steel balls ranges from 40 to several hundred m/s, and their size is approximately 0.05 mm to several mm. A deep hardened layer is obtained by projecting larger steel balls at high speeds, while a shallow hard layer is achieved by projecting smaller steel balls at fast speeds.
