### Materials used in boiler & furnace - SlideShare

From the ASME Boiler and Pressure Vessel Code, Section 18 the allowable stress is that value of stress that given 1% creep in 100,000 hours. Using P, what time will give 1% creep at, not but P = (1050 + 460) (20 + log 100,000) - 37,750 for P at the design temperature of 10500F. Solving the same equation for t when the temperature is 10700F.
