2014/8/1 · This steel is allowed in the ASME Boiler and Pressure Vessel Code for nuclear service up to 371 C (700 F); certain excursions above that temperature are allowed by Code Case N-499-2 (now incorporated as an appendix to Section III Division 5 of the Code).Get Price
For use at temperatures above 1000 o F, the ASME Boiler & Pressure Vessel Code requires a minimum of 0.04% carbon for adequate creep strength. For superheater and reheater applications, the H grade is preferred as this assures the proper carbon content for use at temperatures where creep strength is the important design consideration.Get Price
Indeed, the ASME Boiler and Pressure Vessel Code recognizes creep and creep deformation as high-temperature design limitations and provides allowable stresses for all alloys used in the creep range. One of the criteria used in the determination of these allowable stresses is 1% creep expansion, or deformation, in 100,000 hours of service.Get Price
