In recent investigations (1, 2) it has been observed that sensitized 304 stainless steel may undergo intergranular stress-corrosion cracking in high-purity water at temperatures ⩽100°C when the specimen is being monotonically strained and the oxygen content is in a specific range. In the original tests (1, 2) this critical oxygen range was 1-5 ppm, although other work (3) has indicated that this critical range may be wider. A mechanistic analysis (4) of cracking at low temperatures has led to a satisfactory correlation between the observed crack-propagation rate, at corrosion potentials corresponding to 1-5 ppm oxygen, and the theoretically calculated rate based on a constant-charge criterion (5, 6) for the slip dissolution model of crack advancement.
