Abstract
This study aimed to investigate the effects of difference in nickel content and the tempering temperatures on the corrosion resistance in 13Cr2Ni0.1C and 13Cr1Ni0.15C steels. Results showed that passive film in 13Cr2Ni0.1C steel is formed more quickly at the lowest and highest tempering temperature (650°C and 750°C) but the lowest tempering temperature (650°C) showed better resistance to corrosion pitting. There was passive film formation and pitting corrosion in all tempering temperatures of the 13Cr1Ni0.15C steel and changes in tempering temperature does not significantly alter polarization curves, showing similar behavior to steel 13Cr2Ni0.1C tempered at 650°C.
