The influence of alloying elements on equilibrium precipitation phases of KT5331 were studied by Factsage software and experiment.The results show that the amount of M23C6 carbide is determined by C content in steel.The fluctuation of Cr,Mo content in steel has effect on precipitation temperature of M23C6.The amount of Laves phase is determined by the W content.Based on the influence of alloying elements on the precipitated phase,the influence of alloying elements on the high-temperature endurance property of KT5331 steel was analyzed.The results showed that in order to achieve high temperature durability of KT5331 steel,the C content should be reduced and the Cr and W elements are at the lower level,and the Mo element content is at the middle or upper limit.
