A2 steel in Heat Treating, general discussion Posted April 2, 2020 I've spent $160 in all for the anvil. All thats left, is to weld the A2 steel top plate on. May have enough welding rods left to finish that. If not I'll have to spend another $15 bucks to get more and finish it. Once its welded I'm going to follow the heat treating hardening instructions to harden it. Will build a fire brick pit, then use a couple weed burning torches and propane cooking burner to set the anvil on, add a forced air inlet to it and get it up to temp. Then air cool with some help of water to get it down in temp. fast.
