Ok. So if we put the idea of the salt bath out of mind, how long should I have the steel at 1650 to normalize and do I need to let it come all the way back down to room temp before i austenitize or can I just take it below critical then heat it right back up? Will taking it up to 1650 cause enlarged grain structure or is the final austenitization temp the only thing that matters? Should I be measuring the temp near the burner of the forge or further away? (It's a 2 brick forge with a 3 inch cylindrical opening 9 inches deep)
