摘要：
High-temperature oxidation behaviors of super-clean 9CrMoV steel and 1CrMoV steel for HP steam turbine rotor materials were investigated. The super-clean 9CrMoV steel showed a superior high-temperature oxidation resistance with very small oxidation rates even though at 630 degrees C, because the oxidation was restrained by the Cr-oxides formed near the base metal. On the other hand, the oxide scales formed on the 1CrMoV steel were composed of Fe-oxides, and the oxidation rate increased remarkably at the temperatures above 610 degrees C.
