Quenched and tempered twice. Not entirely pleased with my antioxidation coating. It worked in spots.
The furnace is pretty slow, so it took a couple of hours to get up to the soaking temperature.
I used a blast of compressed air to quench, followed by 2 tempering visits to the slowly cooling furnace. First temper was dark blue, second was dark straw.
Now on to blast and parkerize.
