This is a jewelry kiln I found on Craigslist that goes to 2000 deg F, but looks to be controllable. The mfg literature says it is for glass, jewelry, and metal clay. Heat is heat, but is there a reason this may not be effective for heat treating steel? It has operator programmable sequences that I figure you could program for heat treating. I am not well versed in the matter.

Also- at 2000 degrees could I melt gunmetal bronze in this? I need to cast some gudgeons and pintles for a boat. Mainly I want a kiln for heat treating, but that would be a nice plus.
