An Experiment on Corrosion Fatigue

Abstract

And the fatigue strength decreased markedly after one month's exposure to atmosphere.(2) The fatigue life of SS 41 specimen, subjected to repeated wetting with 3% NaCl and drying under superimposed wave, became very short when the stress of the second wave was very small.This arises from the double effects of corrosion and superimposed wave.(3) The corrosion fatigue test on 13% Cr-Mo steel under varing stress in 3% NaCl showed that the fatigue life decreased extremely as compared with the corrosion life under constant stress.
