Dear All,

I have a question about creep analysis and I would appreciate if an experienced person helped me with.

I know that CAESAR performs creep analysis using code EN 13480, and I have read the part regarding this subject in software user guide,
now my question is about the allowable stress for the materials that are not in EN 13480 and are defined in ASME codes, such as A312 TP304H .

how can I find the allowable stress for 100,000 hour, either by code B31.3 or EN 13480

Thanks,
Shas
