In boiling (140 degree C) 17. 5M NaOH solution the measured crack growth rates of Type 304 did not show any accelerative environmental effect; there was also no significant effect of cyclic frequency, R ratio, or electrochemical potential. The different variables yielded similar fractographic features. For Inconel 600 the boiling caustic solution increased fatigue life relative to life in air, and anodic passivation was beneficial. Sensitization, found beneficial in sodium hydroxide, was detrimental in air. Delay of initiation is primarily responsible.
