This study evaluated the suitability of the depassivator in revealing low degrees of sensitization (DOS) in samples of wrought AISI 347H austenitic stainless steel in the as-received condition and solution heat treated (SHT) at 1050℃. Assessment of the electrolyte composition was performed by the double loop electrochemical potentiokinetic reactivation (DL-EPR) test at room temperature. The electrolyte 1.0M H2SO4 + 0.50M HCl was found to be adequate for detecting low DOS. Microstructural characterization of the as-received material revealed the presence of Cr-rich carbides. These carbides were responsible of the susceptibility to IGC.
