Abstract
Corrosion fatigue tests in NaCl-solution in the temperature range from ambient temperature to 150 degree C revealed a decrease of the corrosion fatigue strength of the steel X20Cr13 with 1% resp. 2. 5% Mo, X4CrNiMo 1651 and zX2CrNiMoN 225 with increasing temperature; a minimum of the corrosion fatigue strength is reached at 150 degree C. At temperatures of about 80 degree C it was found an optimum corrosion fatigue behavior of the Mo-alloyed steel X20CrMo13 2. 5 in comparison with the other investigated steels. All materials investigated failed at elevated temperatures. At temperatures higher than 80 degree C an optimum corrosion fatigue behavior was not found.
