title = "Modeling of creep rupture strength and stress reduction factors for welded 9% Cr steel",
abstract = "Preferred models for creep rupture strength prediction have been evaluated for the parent and cross-weld steel E911, intended for use in headers and steam lines of power plants up to about 600°C. The assessment of the rupture data was performed in accordance with the Guidelines of the ECCC (European Creep Collaborative Committee), using the procedure and models of the standard PD6605. Rupture strength was predicted to a maximum extrapolation time of 160 000 h for the parent material and 50 000 h for the welds. The estimated stress reduction factor (SRF) for welded E911 at 600ºC was about 80% for a rupture life of 21 000 h, and about 70% for a rupture life of 50 000 h. However, the predicted decrease in SRF for longer time and higher temperatures may be exaggerated due to limited long-term cross-weld data.",
