Carbon steel is the most commonly used construction material in oil refining. Ammonium chloride deposition is a well known problem in oil refining. When these deposits form in a moist environment, they are corrosive to carbon steel. When unexpected corrosion problems are faced the material is often changed zn to alloys like stainless steels. The main drawback of stainless steels is that they are prone to different forms of localized corrosion, especially in the presence of halides. In this paper the use of electrochemical measurements to study the corrosion resistance of stainless steels is discussed.
