The paper studies stress corrosion cracking (SCC) of low carbon low alloyed steels. It is shown that the use of eddy current method allows us to evaluate modifications of fine structures associated with the processes of initiation and growth of stress corrosion cracks. The dependences of the incubation time on the value of the macroelasticity limit σ0 are given. It is noted that the increase in the value of σ0 leads to an increase in the time before the initiation of the first crack. This can be explained: the limit of macroelasticity determines the beginning of microplastic flow in the material. On the basis of experimental data, the analytical dependence of the incubation period of the SCC on the value of the macroelasticity limit is obtained. The calculation error did not exceed 10%. A parameter is proposed for assessing the state of the material subject to SCC. It allows recording the passage of the stages of accumulation of micro-damages and the moment of exhaustion of a significant part of the material resource before the appearance of multiple surface macro-cracks according to the data of eddy current measurements.
