摘要：
In order to develop a new rotor forging which has higher mechanical properties than 1Cr-1Mo-0. 25V rotor at elevated temperature, an investigation has been carried out on the mechanical properties and the uniformity of 12Cr-Mo-V-Ta-N model rotor and high and intermediate pressure rotor for a 375 MW steam turbine. 12Cr-Mo-V-Ta-N rotor has better room temperature tensile strength and impact value than 1 Cr-1Mo-0. 25 V rotor in the shaft, body surface and body center. Creep rupture strength is also higher.
