The electrochemical behaviour of AISI 416 and 440 martensitic stainless steel in alcoholic solutions (ethanol, iso-propanol and t-butanol) containing different concentractions of sulfuric acid (0,1 to 2M) has been investigated using potentiostatic anodic-cathodic polarization techniques. An activ- passive transition behaviour were observed and the critical current density (CD) for passivity was found to be dependent on tile concentration of acid in alcohols. The effect of water additions (5, 10, 15%) to IM H2So4 alcohols has been also investigated. It was found that the presence of water strongly influences the passivation of both steels in IM H2SO4 - alcoholic solutions.
