I was just having a conversation about why we only normalize three times. I know why I do it. My three descending cycles set me up to make nice hamons ( I use 1075, W-1, and W-2 steels 99.99999999% of the time). It also seems to make my grains very nice and fine when I work 80crv2. I am lazy, and I didn't have to change any settings on my HT oven for my normalization cycles when I want to change over to 80crv2. That's why I do it. The person I was discussing this with said there was no way to over normalize steel, you could do it as many as you wanted, and the steel would harden. The reason we don't do it any more than three is there was no point. After three times the steel gained no more benefits, because the grains were as fine as they could get. This made since to me, but I could have sworn that a long time ago I think it was Kevin Cashen (memory has become an issue after an incident) circa 2005, said that too many nomalizations can lead to it becoming difficult to harden. Of course in the discussion I had completely forgotten about alloy banding. Are there any charts I can look at regarding this normalization not hardening phenomenon? It has been crazy trying to find anything online.
