First want to say hi to all. New guy here. Not sure if this is the right place but I have a heat treat question. I'm in a small, small shop with limited resources. I have made a small piece out of 1045 steel, 25mm OD, tapers to 7mm and 25mm long, I use to press sleeves into another part. The metal sleeve is also 1045. It has a .5 step and after a while the little step on the pressing part wears and gets out of shape. I'd like to harden it to last longer. As I said I'm limited on what I have available but we do have a set of torches here and wondered if I can use them to heat it up to a glowing red and then dip it in water . Would that give me some hardness or make it brittle? Thanks.
