  1. 1.

    In the lower region of the dangerous temperature range the development of intercrystalline corrosion in austenitic steels does not depend on the carbon concentration and is accelerated with increasing chromium concentrations. These results cannot be explained by the impoverishment theory. They are quite well explained if we assume that susceptibility to intercrystalline corrosion in the lower region of the dangerous temperature range depends on the diffusion rate of chromium.

  2. 2.

    In the upper region of the dangerous temperature range the time necessary for development of intercrystalline corrosion decreases with increasing carbon concentrations; it increases somewhat with increasing chromium concentrations.
