Harder material has a tendency to be more brittle. In a location that is going to constantly heat cycles, I'm not sure you want to have it be harder. I know we are very selective where we use high strength materials offshore.

But do consider that people (like Cosmo) cryo-treat their blocks, pistons, rods, etc, and all of those endure tons of heat cycling.
