A514 (T-1) steel seems to possess remarkable
properties, being 100,000
psi strong, and yet has a very unremarkable
composition. A little
vanadium and a little chromium. What exactly is it,
that makes it so strong?

Carbon...

Carbon for strength, and vanadium/chromium for toughness?
Many hand tools/wrenches are chrome/vanadium steel.
