For life extension of fossil power plants, one of the most important subjects is to evaluate creep damage in high-temperature components such as boilers and turbines. In the life prediction, hardness is very important, because it has good correlation with some properties of materials and it is easy to measure it. Until now, hot hardness hasn't been used for the life prediction. This paper reports the availability of using hot hardness for more accurate life prediction technique.
