This paper first briefly introduces the history for the development of China valve steel from mainly adopting the valve steel of former Soviet Unoin in fifties, manufacturing by oneself in sixties, and introducing advanced valve steel from othe rcountries and instituting Chinese valve steel system since seventies. The demand of valve steel for China internal combustion engine including mateiral specification and quantity required at present is discussed. the principal difficulties being faced with the developed of China valve steel at the moment are put forward. Lastly, a detailed discussion is made on the development of China valve steel, making suggestions as follows develop 5Cr8Si2 and MF811 for martensitic steels, develop 21-2N for austenitic steel used for gasoline engine, develop 23-8N for austenitic steel used for diesel engine, develop 21-4NWNb for highs trength austenitic steel and develop LF2 and LF4 for valve alloy.
