The corrosion behavior of constituent metals (Fe, Cr, Mo) of iron-base and nickel-base alloys has been examined in 5 mass% NaCI at temperatures of 300-450 °C and at a constant pressure of 30 MPa. The mass changes of pure Cr are very small in the range of 300 to 450 °C
and their magnitude is close to the limit of detection, whereas pure Fe and Mo show significant mass losses at temperatures of 300 to 450 °C. The mass loss of pure Fe is higher than that of pure Mo at 300-350 °C, but is lower at 400-450 °C. The oxide films...
