【Abstract】 The development status of materials for high temperature castings of foreign steam turbine has been discussed. Meanwhile,the difference of manufacturing process between 9% ~ 12% Cr ferritic heat-resisting steel and nickel base alloy castings and low content alloy castings has been analyzed and compared. Eventually,the development trend of materials for high temperature castings of ultra supercritical steam turbine in China has been pointed out.更多还原
