    Just because it’s red hot does not mean it’s near molten. The material still has sufficient proprieties to support its weight.

        It should be. If you heat it all the way through, you get more heat-stress. Ideally, you only want the outside hot (and then cold again) to surface-harden it. You don’t need the middle bits hardened, after all.
