The paper briefly describes the early phases of the development in the electrochemical potentiodynamic reactivation method – EPR – for measuring the degree of sensitization or structural transformation in stainless steels. By using the reactivation procedure from the full passivity region one can assess the tendency of the respective type of steel for intercrystalline corrosion. The process of measuring using reactivation from the incomplete passivity region indicates local changes in chemical composition in relation with the phase transformation.
