I want to find allowable compressive stress (ASEME section VIII Div 1 vessel) for SA 387 material (1.25% chrome plate) at 1250°F. Stress tables (although those are for tensile stress) in Part D stop at 1200°F. Any WRC bulletins give any methodology to find what I am looking for?

ALLOWABLE COMPRESSIVE STRESS

You're probably out of luck. You're definitely in the creep regime. And since you're interested in compressive stresses we're obviously talking buckling failure. Let me tell you - creep buckling is an extremely difficult phenomenon that barely a few experts have been able to get a handle on. I woudl stay away from that failure mode at all costs.
(You'll note that the allowable compressive stresses in Sec. II, Part D even stay away from the creep regime - with a healthy margin!)

Any research papers on this issue? I am sure there are a few thesis written about this topic. Any references will be highly appreciated. I am also sure that WRC has done some work on this topic. Any bulletins that you know of that tackle this issue?
