摘要

Today, extensive knowledge-base and data-base are available on popular grades of low alloy steels of Cr-Mo and Cr-Mo-V types. But, what is still Jacking is a mechanism based creep life prediction methodology. The present paper attempts to clearly bring out the predictive strengths of two potent parameters: the threshold stress (#sigma#_H ) and the creep damage tolerance (#lambda#).The findings are based on systematic study carried out on a Cr-Mo-V main steam pipe line both in the virgin and service exposed conditions. Finally, a life prediction methodology based on #sigma#_H and #lambda# has been proposed for straight pipe lines of the low- alloy ferritic steels.
