Creep properties 700°c
WebAug 6, 2024 · Therefore, the present study evaluated high-temperature creep properties of NH2 at around the operation temperature, 700 °C–800°C. The degradation of creep properties, such as shorter rupture time and enhanced creep rate, were observed for NH2, compared with a conventional US heat in the stress range of 150–200 MPa. WebThe creep results for oxide-dispersion-strengthened (ODS) ferritic steels at 650 and 700°C showed no difference in the creep rupture strength when tested in static sodium and in inert gas. 76,77 However, a loss of creep rupture strength in sodium was observed in 2.25Cr–1Mo steel due to decarburization. 78
