Abstract��he creep rupture strength and endurance plasticity of stream��turbine cylinder steel at 593 �� was studied. Linear fit was done at log��log coordinate of creep rupture strength and time, and get the creep rupture strength of 10��5 h for the heat resistence steel by meansd of extrapolation .The change of endurance plasticity with the rupture time was analysed and discussed .The microstructure before aging and after 5��KG-*9��600 h aging was observed and analysed by metallogragh and SEM.
