Materials/standards for high temp/pressure vessel...
(OP)
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 design said vessel ?
We will probably bring a consultant into this project. I want the above information to get background on the problem before we do.
Thanks.

Despite the small volume (250 ml) this type of vessel should be designed and fabricated in accordance with ASME Boiler and Pressure Vessel Code or an equivalent foreign standard (outside of the US).
The particular section of the ASME B&PV Code that you should use is Section VIII, Div 1, which applies to unfired pressure vessels.
My suggestion is to indeed hire the necessary expertise for pressure vessel design to Section VIII. Regarding suitable materials, ASME B&PV Code, Section II provides a comprehensive list of materials based on use at service temperature. At 1600 deg F your alloy selection will probably be limited to Ni base (non-ferrous) alloys.

Some of the super alloys will go to higher temperatures, but the cost doesn't seem worth it at this time.
I don't see any values for 316Ti. Does anyone know if they would be higher ? (Just curious, not saying we would use it anyway...)
Thanks.
