    Yield strength for P11 at 1050F

    metengr, Do the YS you have for 1000F and below match table Y? The YS at 1000F is 21.9ksi. The 16ksi seems to be a large drop for 50F. corky48

    Yield strength for P11 at 1050F

    Frank, ASME B31.3 now allows an alternative allowable stress for occasional loads for temperatures greater than 800F. However it references the yield strength at temperature in Table Y in Sec II Part D. Unfortunately the table goes to 1000F and my line is 1050F.
