In order to improve reliability of components for thermal power plants and petrochemical plants, long-term creep tests are performed for heat resistant steels and alloys. Our goal is to obtain 100,000h creep rupture strength because allowable stress is determined based on the 100,000h creep rupture strength. NIMS Creep Data Sheet has been published since 1972. Metallographic atlases and fracture-mode maps of heat resistant steels are also published based on the results of microstructure observations of creep ruptured specimens. We have 500 single-lever creep testing machines. Emergency power generator can supply electricity to the creep testing machine when a power failure occurs. Recently, review paper for creep data sheet has been published.
