The Science of Shot Peeningalmen testing

No operation is precise or scientific if it can’t be measured.  In peening processes, intensity is measured using precisely made steel test strips (Almen Strips) and a gage to check how much the strip deforms when it is peened.

As one side of the strip is bombarded by peening media, the resulting compressive stress on that side causes it to curve into an arc.  Measurement of that arc will reveal if the peening process is set up correctly to match the specs of the job.

Almen strips are most commonly manufactured in three thicknesses, A, N and C types.  They are  further separated by class and tolerance for straightness for use in different job applications.  A&B Deburring offers a comprehensive selection of Almen strips to meet most common and specialized specifications
