In the present paper the corrosion behavior of 2 1 / 4 Cr1Mo steel, Alloys 800H, AC66, 45TM and 690 was investigated at 300 to 800 °C in dry air and synthetic air with 2 vol.‐% Cl 2 . The data reveal that the major role determining corrosion resistance are played by Fe in the alloys. In particular if the same Cr‐contents are present in the alloys it is only the Fe content which decides on resistance against Cl‐attack while additions of even almost 3 % of Si evidently have only little effort.
