Description

This International Standard describes the requirements for automated, controlled shot-peening of metallic articles

prior to electrolytic or autocatalytic deposition of nickel or chromium, or as a final finish, using shot made of cast

steel, conditioned cut wire, ceramic shot or glass beads. The process is applicable to those materials on which test

work has shown it to be beneficial within given intensity ranges. It is usually not suitable for brittle materials. Handpeening

and rotary flap-peening are specifically excluded.

Shot-peening induces residual compressive stresses in the surface and near surface layers of metallic articles, and

changes the surface microstructure (including phase transformation), thereby controlling or limiting the reduction in

fatigue properties that occurs from nickel or chromium plating of the article, or increasing the fatigue properties of

unplated articles.
