Abstract:  
Shot Peening is usually considered as a sensible method to prevent cracking related to fatigue or stress corrosion. In this paper I present the results of static stress corrosion tests of three austenitic materials. The specimen for tensile test were made from the material 1.4571 ( X 6 CrNiTi 17-12-2 ), 1.4541 ( X 6 CrNiTi 18-10 ) and 1.4462 ( X 2 CrNiMoN 22-5-3 ). The different shot peening parameters were selected by the Peenstress sm Software. The calculated and measured residual stress profiles are very close.
