Thermolyne Electric Kiln Furnace 2000 deg F - $100 (watsonville)

I've got a similar furnace that takes 115V. It works great for heat treating small punches and dies (4" x 4" x 9" chamber). Takes mine about 30 minutes to heat up to 1500 F for hardening steel. It draws around 2200 W or about $0.15 to heat steel to red hot in the 30 minutes. They are pretty well insulated, can hold my hand on top of the furnace at that temp. Quite a bit cheaper than using oxy-acetylene for hardening small items.

I recall paying around $200 for mine which is in quite a bit better shape than the one pictured. Looks aren't everything if it's in working order.

I have a larger Thermolyne furnace and it works well I paid about $100 for it. Has old school control but reaches temperature quickly.

Outside barely gets warm and take about a day to cool down from 1200 degrees

I don’t have any other heat treat ovens but it works well in my opinion
