martensitic steels. Universality of correlation dependence between the operational
changes in brittle fracture resistance and in polarization resistance for carbon and
low-alloyed ferrite-pearlite steels of a number of critical metal structures, which does not
depend on their operation conditions, has been determined, that facilitates the method
practical application.
Keywords: structural steels, technical condition, electrochemical nondestructive
method, informative feature of degradation, operation, corrosion-hydrogenating
environment, damaging, delamination.
