Tests have been done on cyclic corrosion cracking resistance in 34KhN1M steel used for making steam turbine disks in distilled water with the addition of 1.2 mg/liter of NaCl and KOH. to pH 9.3 with loading frequency f of 0.017-1 Hz and temperatures of 293-368 K under constant electrochemical conditions at the crack vertices or with allowance for changes occurring there. Measurements have been made on the trends in the electrochemical characteristics at the vertices of static and growing cracks during corrosion cracking tests. The extremal working and electrochemical conditions have been determined and a quantitative evaluation is given for the extents of the local anodic dissolution and hydrogen embrittlement occurring at the vertices of static and growing cracks.
