<p>This International Standard describes the requirements for automated, controlled shot-peening of metallic articles</p>
<p>prior to electrolytic or autocatalytic deposition of nickel or chromium, or as a final finish, using shot made of cast</p>
<p>steel, conditioned cut wire, ceramic shot or glass beads. The process is applicable to those materials on which test</p>
<p>work has shown it to be beneficial within given intensity ranges. It is usually not suitable for brittle materials. Handpeening</p>
<p>and rotary flap-peening are specifically excluded.</p>
<p>Shot-peening induces residual compressive stresses in the surface and near surface layers of metallic articles, and</p>
<p>changes the surface microstructure (including phase transformation), thereby controlling or limiting the reduction in</p>
<p>fatigue properties that occurs from nickel or chromium plating of the article, or increasing the fatigue properties of</p>
<p>unplated articles.</p>
