Searching for a Metal with High Modulus
Searching for a Metal with High Modulus
(OP)
I am in need of a metal that can be compressed repeatedly (preferably thousands of times) to approximately 95% of its overall height, and rebound to near its original height. It must do this in a constant 400F degree environment.
Any suggetions are greatly appreciated.

20,000 psi is not a force, it is a stress or pressure.

(And they stock 17-7 wich is useable till 600F or so. (and unless you need a bunch, will be not too expensive)

You are looking for something that can withstand an elastic strain of 0.95 for thousands of cycles at 400 °F. That kind of strain is practically impossible in a metal. Elastomers are the materials of choice for high elastic strain, and there may be some fluoroelastomers that can withstand 400 °C. Try Dyneon or DuPont:
