IRL early steel was made by adding carbon in the form of powdered charcoal to the molten iron. Ingame there is charcoal to be found but it is without any use whatsoever. I can only suppose it was intended for making steel but it was abandoned for some reason and replaced with corundum. And since there is no copper ingame, and copper was the very first metal in history to be used for weapons i think corundum is copper. The ore has the right color and it even has greenish veins wich seems to mimic the color of copperoxide quite closely. (whereas iron ore ingame had veins of ironoxide color) It might be a longshot, but i think they had to drop charcoal functionality and hastily replaced it with copper, and since everyone knows mixing iron with copper will definately not get you steel they renamed it to corundum.
