SAE AMS-S-13165

Description / Abstract: Shot peening is intended to induce surface compressive stresses in metal parts which are subjected to repeated applications of complex load patterns such as axles, springs (helical, torsional and leaf), gears, shafting, aircraft landing gear, structural parts, etc., for the purpose of improving resistance to fatigue and stress corrosion cracking. Ceramic and glass bead peening, either wet or dry, is used when iron contamination of non-ferrous parts is a consideration
