We have a reaction that we would like to occur at high temperatures, preferable around 1000C. This creates a problem in that most (all ?) alloy design pressure must be derated due to creep rupture issues.
Is there a spec or has anyone designed an internally insulated pressure vessel wherein...
This webpage says that 316H has a "short time" tensile strength of 120MPA at 900C.
It also says that for a creep of less than 1% in 10,000 hours at 800C the pressure should be kept below 20 MPA.

Could someone explain the relevance of these...
We need to build a small (250ml) test vessel that holds steam at 2000 PSI and 1600F or thereabouts. On first look, we are thinking of using 316H stainless.
a) what is the best guide to the stress/temp abilities of various steels, such as 316H.
b) what ASME documents should we be using to...
