This paper reviews the data needed to develop fatigue design rules for pressure vessels fabricated from heat-treated 2-1/4Cr-1Mo steel (SA-387, Grade 22, Class 2 plates and SA-336, Grade F22 forgings) that are operated or designed to operate at temperatures greater than 371 C (700F). The available data were reviewed, and the results of that review were used to develop recommendations for needed analytical and experimental work. Extension of the fatigue-curve approach currently used for temperatures up to 371 C (700F) and development of a fracture-mechanics-based, crack-growth approach were addressed. Both of these two approaches must include means for assessing the time-dependent effects of oxidation and/or creep when fatigue cycling occurs at low stain rates or includes hold times. The recommendations of this study provide a plan for the development of fatigue design rules for the use of heat-treated 2-1/4Cr-1Mo steel at temperatures in the range of 371 to 482 C (700 to 900 F).
