摘要： Disclosed is a low alloy steel which has a defined chemical composition and has a metal structure composed of bentonite or martensite. In the low alloy steel, the timing of deoxidization or addition of Nd in the steel metal dissolution process is properly selected to allow an Nd inclusion to be present in a proper amount. Thus, the low alloy steel can achieve both a high temperature creep strength and a long-term creep ductility even under severe environments, which has been hardly achieved by a conventional steel. The low alloy steel can be widely used as a material for a heat-resistant structural element which is used under high temperature/high pressure conditions for a long period of time, such as a power plant boiler or turbine and a nuclear power plant.

摘要： According to a low alloy steel of the present invention, compositional elements thereof are limited, and a metal structure thereof comprises bainite or martensite. Further, a proper amounts of Nd inclusions are formed by appropriately selecting timings of deoxidation and Nd addition in melting a steel. Consequently, compatibility between high-temperature creep strength and long-term creep ductility, which is hardly established in conventional steels, can be achieved even in hostile conditions. Accordingly, the low alloy steel of the present invention can be widely applied as the material for the heat-resistant structural member used for a long time under the high-temperature and high-pressure conditions such as power plant boilers, turbines, and nuclear power plants.
