I *probably* could have done it without heating the rod first, but ah
well... heating it was more fun.

If you didn't even get it glowing, you didn't really do much to it. To
really see the effect of heat on steel, you need to get it up a good 2000F
(yellow) or so. The things you can do...


The effect will be pretty obvious at 1100-1200F, where yield will be 30-
50% of yield at room temperature. At 2000F it'll be 5% or less. But it's
true that there won't be much change before the steel starts to show
some color.
