pipe/tube material grade selection chart/webpage/book???
(OP)
I was wondering if there is a good resource for selection of materials based on operating temperatures... right now we are working on selecting a grade of steel for piping, but also I regularly pick material grades for bar stock, tubes, and others as well. I base a lot of my picking on code requirements, but sometimes the code only tells so much. Right now I would like to get some welded pipe for some natural gas that will be at an average temp of 600 degree F... this is not that hot, but in the future we may make the same product for up to 1200-1500F so I was hoping on finding a material grade/temp chart or something... I see some astm standards refer to products that are meant for high temp service but they do not seem to specify what they mean by high temp and also I believe this is for the strength of the material or does this also refer to creep and high temp corrosion and such too... for instance I would rather use an A312 gr. 304L pipe for a pipe exposed to the furnace in a boiler rather than a A106B even though the A106B says for high temp service correct? But there are so many alloys available... I am wondering if there is a resource available to help make selections easier. Thanks.

are just a few.

The other half of what you need to know are the effects of service environment on the behavior of candidate pressure retaining materials. This gets to be a little trickier because knowledge of the service environment is necessary to ensure proper selection of material for service.
The advice in the above post is fine for material suppliers that have the technical staff with experience in selection of materials and their behavior. Otherwise, you as the designer, need to conduct your own research on material behavior in process streams.
Let me know if you find a one size reference that fits all because I sure could use one.
