Stainless steels are the workhorse alloys of aggressive industrial applications. Stainless steels may exist as ferritic austenitic and duplex materials. Stainless steels are obtaining by adding chrome into iron alloys. Other elements such as molybdenum are also added to increase the resistance of these alloys to localized corrosion. Localized corrosion is generally caused by the concentration of chloride ions in localized spots of the metal. This paper will review the effect of the alloying elements on the microstructure and the resistance to localized corrosion both from the point of view of initiation and repassivation.

Keywords: stainless steels, ferritic, austenitic, passivation, localized corrosion, chloride, temperature
