Author Jurgen Kritzler, Metal Improvement Company, Inc.; Unna, Germany Abstract Shot Peening is usually considered as a sensible method to prevent cracking related to fatigue or stress corrosion. In this paper, I will present the results of static stress corrosion tests of three austenitic materials. The specimens for tensile testing were made from the materials 1,4571 (X6CrNiTi17-12-2), 1,4541 (X6CrNiTi18-10) and 1,4462 (X2CrNiMoN22-5-3). The different shot peening parameters were selected by the Peenstress Software. The calculated and measured residual stress profiles are very close.
