摘要： A high Cr ferritic heat resistance steel which comprises as components, in mass %, C: 0.08 to 0.13 %, Cr: 8.5 to 9.8 (10.2) %, Mo: 0 to 1.5 %, V: 0.10 to 0.25 %, Nb: 0.03 to 0.08 %, W: 0.2 to 5.0 %, Co: 1.5 to 6.0 %, B: 0.002 to 0.015 % and N: 0.015 to 0.025 %, and optionally one or more of Re: 0.01 to 3.0 %, Si: 0.1 to 0.50 %, Mn: 0.1 to 1.0 %, Ni: 0.05 to 0.8 % and Cu: 0.1 to 1.3 %. The heat resistance steel exhibits significant improvement in long term creep strength, which results in the production of a turbine rotor and turbine parts used in an electric power generation system allowing the use of a steam of an elevated temperature, leading to the improvement of the efficiency of power generation. Further control of the composition based on the parameter for suppressing the acceleration of creep allows the retention of high creep strength for an elongated period of time.

Specifically, the d-electron orbital energy level (Md) and the bond order (Bo) with respect to iron (Fe) of each alloying element of a body-centered cubic iron-base alloy are determined by the Dv-Xα cluster method, and the type and quantity of each element to be added to the alloy are determined in such a manner that the average Bo value and average Md value represented respectively by the following equations: coincide with particular values conforming to the characteristics required of the alloy; wherein Xi represents atomic fraction of an alloying element i, and (Bo)i and (Md)i represent respectively the Bo value and Md value of the element i. Preferably, the average Bo value and average Md value are, respectively, in the ranges of 1.805 to 1.817 and 0.8520 to 0.8628.

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.
