We study the influence of gas-turbine fuel ash and gaseous hydrogen on the mass losses caused by longterm corrosion and the mechanical properties of heat-resistant CM-88U-VI, CM-90-VI, and CM-104-VI cast blade materials. It is shown that the level of sulfide-oxide corrosion resistance of the investigated alloys (CM-104-VI > CM-90-VI > CM-88U-VI) correlates with the chromium content. The highest resistance (among similar materials) is exhibited by CM-104-VI alloy, especially for long-term hightemperature tests. The CM-90-VI single-crystal alloy proves to be least sensitive to the action of hydrogen in short-term tensile tests carried out within the temperature range 20–900°C under a pressure of 30 MPa.
