Where can I find Elevated Temperature Properties for various grades of Graphite? PGX, HMM, HMR, etc?
Namely, Coefficient of Thermal Expansion and any Strength Properties at roughly 1550 deg F.
One of the best books at answering any type of question related to machines, and properties of materials is “Machinery’s Handbook”…I think they are on the 28th or 29th edition by now. You can get one at Graingers or MSC supply.
