Abstract

In the field of CrMoV heat-resistant alloys for use in turbine rotors, in order to provide a low-alloy steel which has a toughness at the same level as conventional materials and has excellent high-temperature strength properties, particularly inhibition of creep embrittlement, and in order to provide a process for producing such a low-alloy steel and a turbine rotor in which such a low-alloy steel is used, trace impurities of phosphorus, sulfur, copper, aluminium, arsenic, tin, and antimony in a CrMoV heat-resistant alloy are reduced to specific levels or lower. In addition, trace impurities such as cobalt, niobium, tantalum, nitrogen, and boron are added to increase the creep strength according to a test using an unnotched test piece. In addition, according to the production process, quenching is carried out after heating to 1000 DEG C or higher so as to inhibit precipitation of pro-eutectoid ferrite phase.
