摘要： In the thermal power system, the electricity production efficiency may be improved by providing turbine members having the improved high temperature characteristic over the corresponding prior art turbine members. Turbine members may be provided by using high resistant steels composed of any one or ones selected from the group consisting of the components, including 0.08 to 0.13% of carbon (C), 8.5 to 9.8% of chromium (Cr), 0 to 1.5% of molybdenum (Mo), 0.10 to 0.25% of vanadium (V), 0.03 to 0.08% of niobium (Nb), 0.2 to 5.0% of tungsten (W), 1.5 to 6.0% of cobalt (Co), 0.002 to 0.015% of boron (B), 0.015 to 0.025% of nitrogen (N), and optionally, 0.01 to 3.0% of rhenium (Re), 0.1 to 0.50% of silicon (Si), 0.1 to 1.0% of manganese (Mo), 0.05 to 0.8% of nickel (Ni) and 0.1 to 1.3% of cupper. The long-time creep strength may be improved by using those high resistant steels for turbine rotors, turbine members and the like, which enable the steam temperature to be higher, thereby improving the electricity production efficiency in the thermal power system. The accelerated creep inhibitor parameter is provided for controlling the reduction in the creep strength so that the high creep strength can be maintained for the extended period of time.
