Atmospheric corrosion of martensitic stainless steel parts

Abstract:

This paper describes a study conducted to determine the causes of the low atmospheric corrosion resistance presented by several valve cones made of martensitic stainless steel for petrochemical industries. The cones presented a severe atmospheric corrosion over a one-month storage in a wet industrial atmosphere. It has been found that this low corrosion resistance was a consequence of a carburizing process of the material during the heat treatment. An analysis of the causes of the low corrosion resistance of the carburized layer is presented.
