Kurzfassung englisch:
The microstructure determined by metallographic investigations and the electrochemical potentiokinetic reactivation test (EPR test) revealed sensitization of a stainless steel of type X12Cr13. The original steel contains ferrite, some martensite and carbides but also MnS and Ti(C,N) inclusions were observed.
A carbide solution annealing and several other heat treatments were applied to modify the microstructure of the steel and the EPR behaviour. The various microstructures, which were observed after heat treatments, could be correlated with the results of the EPR tests.
Some unusual EPR results and rather wide scattering of data could be correlated with the dissolution of MnS in the H2SO4 based electrolyte. These effects could be reduced by a pre-treatment of the steel with H2SO4 prior to the EPR test.
