Abstract A creep life consumption study was conducted in a high-pressure turbine rotor belonging to a 363 MW thermal power plant. The component is manufactured with 30CrMoV412 steel, which is a typical 1CrMoV forged rotor steel, having operated for 112,000 h, under a pressure of 17.6 MPa and temperature of 520 °C. The main objective of this paper is to evaluate the applicability of hardness tests as a tool for structural integrity analysis in the field. Two methods for estimating creep remaining life based on hardness measurements were used. Furthermore, metallographic replicas made during unit shutdown were observed by scanning electron microscopy, in order to detect creep voids and also to corroborate the results for accumulated creep damage obtained based on hardness measurements.
