Homemade Heat Treat Oven

Thanks a lot for watching i hope you liked the video.
Homemade heat treat oven. From a few online guides to heat treat 1084 steel you need to get it up to around 815 c around 1500 f. Folow me on instagram. Waiting on the bricks to get here. Also got the control box built and wired up.
The foil acts as a hermetic seal that keeps oxygen away from the surface of the steel while it is at carburization temperatures. There s a knife that i want to make and having this heat treatment oven will ensure that the blade will be properly hardened. Links to amazon products can be found here in my affiliat. I m using some flat stock that is around 3mm thick 0 125 so i probably need to hold the steel at the hardening temperature for 5 7 minutes.
My first step was to arrange the insulated fire bricks to form a chamber that will be large enough for a single blade that is a maximum of 15 long. Apr 12 2016 decided to build an oven. Finally made a proper heat treatment oven capable of reaching 1000 c 1800 f drawing only 1 7kw. To thwart the effects of oxygen a gas blanket say nitrogen can be used to purge the oxygen from the oven or a simple foil pouch of stainless steel can be used.
