T he beneficial characteristic of low-S i steels, lillie segregation and homogeneous mechanical jJroperties in large ingots, was applied to a 12Cr steel.The studies of the microstructures and creep ruft ture p roperties for a low S i-12Cr-1.5Mo-O.2V-0.05Nb steel after various heat treatments were carried out.T he creep recovery mechanism, the precipitation characteristics of M 23 C s alld the dissolution and coagulation of the fine p recijJitates were investigated by the aid of transmission electron microscope.Furthermore, the ~ffects of prior tempering temp erature and creep stress on the microstructures and mechanical properties were also investigated.T his steel exhibits a superior creep rup ture strength, 1.4 times that of the cOllventional super 12C r rotors.T he austenitizillg temperature ~ffective for the lOllg term creep strellgth was foulld to be ill the ra nge of 1 050° to 1 100 0 e alld optimum prior tempering temperature was about 700°C.
