Interesting shit. Took a little detour into an X-53 steel rabbit hole and ran across this (techsteel.net). Scroll down a bit and look at the thermal properties. Never seen precise expansion coefficients like these attributed to multiple specific temperature ranges. Of course I've never spec'd ultra high strength steel (140 KSI) for use in military aircraft either.
A good read. You've really got your nerd/geek on today!
