Abstract

A series type 316 stainless steel (SS) containing various amounts of Ce was prepared and the effects of the Ce addition on the sensitization properties were investigated. The material with 0.01 wt. % Ce showed lowest reactivation ratio for a given heat treatment in the initial and intermediate stages of sensitization. Ce addition influenced the precipitation sites of carbides and decreased the sensitization kinetics including the recovery stage. Both the sensitization and the low temperature sensitization behaviors were similar for the Ce modified materials, indicating a beneficial effect for steels containing 0.01 wt. % Ce.
