Abstract In the present work, the effect of prior austenite graiain size upon the stress corrosion cracking(SCC) and corrosion fatigue (CF)of 40CrNiMoA steel in distllied water was studied. The impurity segregations at grain boundaries of various prior austenite grain sizes resulted from different heat treatments were analysed by using Auger electron spectroscopy. The initial crack areas of fracture surfaces after either SCC or CF tests were observed under SEM. It was concluded that the behavior of both SCC and CF of 40CrNiMoA high strength steel in distilled water, in terms of its crack initiation as well as crack propagation, was mainly associated with the grain size, and the cracking modes were dependent upon the interactive relation between the grain size and the plastic zone ahead of the crack tips under tri-axial tensile stressing condition, thus determining the susceptibility to cracking.
