Many researchers are focusing on the candidates material used for HP and IP rotor. New developed ferritic and aus- tenitic heat resistant steels promotes the construction of 600 ℃USC power plants. But ferritic and austenitic steels cant be used for high temperature components of 700 ℃USC plants ，and nickel based alloy must be considered. The technologi- cal characteristics of heat resistant alloy used for 700 ℃USC steam turbine rotor were introduced. The latest research re- sults on material selection and commercial manufacture in Europe，America and Japan was reviewed. Moreover ，the de- velopment of heat resistant alloy for 700 ℃USC turbine rotor in China was discussed. Key word
