Power plants have a broad need to use the alloys with the ability to work in high temperatures. Increase of efficiency of a plant requires working at higher temperatures and therefore using stronger alloys. Steel super alloys which have different contents of alloying elements are mainly used for working in plant working temperature range (600 °C). These steels have special alloying elements which provide high strength and long life in the high working temperature. Development of these alloys needs knowledge and expertise in these alloys and the mechanism by which they improve the properties of the steel. In this presentation, different alloying elements which are used in the creep resistant steels are discussed.
