Conclusions

1.
The corrosion resistance of chromium steels in superheated steam depends on the amount of chromium the steel contains. Steels with 5% Cr lose the greatest amount of weight in corrosion tests at 500°C, steels with 2% Cr at 550°C, and steel with 1% Cr at 600°C. The corrosion resistance at all temperatures increases when the concentration of chromium is 13–14%.

2.
Silicon increases the corrosion resistance of low alloyed steels in superheated steam particularly when its concentration is 0.01–0.4%.
