Abstract The surface film on Si-bearing stainless steels formed aftersoaking in concentratednitric acid for 216h was investigated by means of electron energy spectrum analysis. It canbe reached from this investigation that Si builds up in the surface film in the form of silica.It plays as a main passivating element in Si-bearing stainless steels in strong oxidizing medium,whereas Cr drops into the second place.
