As a hobby blacksmith, I know that pounding on a piece of cold metal will make it hot. Some smith even show off by lighting cigarettes that way, though I've never seen that in person. But you have to deform the metal a lot to get it hot -- for example forging the square end of a bar into a point.

I'm pretty sure that steel absorbs very little energy simply by being stressed; it only gets hot through plastic deformation. Otherwise, think what would happen to the connecting rods and valve springs in piston engines, for example.
