In this study, failure of the cone of a reactor in an ethylbenzene unit of a petrochemical complex has been investigated. The material of the cone was found to be ASME A240 Type 304H which was severely corroded at elevated temperature. The study of the microstructure of the material showed the occurrence of carburization which led to sensitization and resulted in corrosion of the material. The result of the microhardness testing and double-loop electrochemical polarization investigation proved the diffusion of carbon through the material and occurrence of sensitization.
