1) Remark: According to Werkstofftabellen der Metalle, published by Alfred Kröner Verlag Stuttgart 2000, the material G-CoCr28Mo with the material number 2.4691 shows resistance against high-temperature corrosion (sulfidation) the resistance against oxidation is lower than that of nickel alloys. The material is applied for construction components for the furnace construction, the chemical and petrochemical industry as well as for gas turbine and jet engines with a high demand on the high temperature tensile strength, such as blades, flame tubes, combustion chambers, afterburners, inlet nozzles, discs, rings, high-temperature valves and springs.
