The valve stems as the key component of the nuclear power plant control the power output,their performance directly affect the situation of operation of reactor.In this study,the 17-4PH stem materials were taken from VVP main steamsystem of a domestic pressurized water reactor nuclear power plant.VVP-1,2 and 3 were the main steam isolation valves for service of 11,14
