Pure Mo and type 304L stainless steel powders were mixed to form type 304L with 2.5 mass% Mo and were subsequently sintered to fabricate a stainless steel containing Mo-rich phases. After sintering, heat treatments were performed at 1573K (5 h) and 1373K (0.5 h). It was confirmed that Mo- and Cr-enriched secondary phases were generated. Potentiodynamic polarization was conducted in 0.1M NaCl. The pitting potential of the stainless steel containing Mo-rich phases was higher than that of the commercial type 316L sheet (non-sintered steel). The results of this study clearly indicate that the existence of Mo-rich phases in sintered stainless steels improves their pitting corrosion resistance, making them highly suitable for use in chloride environments.
