Abstract Due to the particularity of dimensions and working condition,the high and medium pressure rotor forgings have been the major critical component with milestone significance in the process of technological development of ultra-supercritical units. Nowadays,9%-12%Cr martensitic heat-resistant steel is widely used to produce the high and medium pressure rotor forgings for 600-620 ℃ ultra-supercritical units. The developing history of 9%-12%Cr heat-resisting material for the high and medium pressure rotor forgings in recent 60 years was comprehensively discussed. For high and medium pressure rotor forgings with different service temperatures,the material selection, chemical composition and strengthening mechanism of forgings are emphatically introduced,and the difficulties and key points of smelting process,forging process and heat treatment process in engineering manufacturing process are briefly described,which provides guidance for the engineering manufacturing of high and medium pressure rotor forgings of ultra-supercritical units at 600 ℃ and above.
