Heat Treating Stainless In A Forge?

If i can get my forge to run at a consistent temperature over an extended period of time(15-30 min) could i heat treat stainless in it and have it come out properly?Thanks

On of the issues is stabilzing time. That's where you let the steel 'soak' at a lower temperature on it's way up to the top temp. Not required (by experience), but recommended.

I've often thought about doing this. IF you can get the forge to hold a temperature this might work on small blades. Carve a cavity in a soft insulating block the will fit the knife with the foil wrap. Get the forge up to temp. Place the blade in the block. Then put the block in the forge. The block will slow the heatup process and even out the temp. Even better would be to install a thermocoupler in the block to monitor the temperature that's getting to the blade.

Of course I haven't tried this, but it feels like it would work. I'd like to hear from someone that's tried.

I thoroughly searched these forums and i found one post by Ed Caffrey that he was heat treating small s30v blades in his forge. I am very interested in what others have experienced. I can get my forge(forced air and propane )to run for extended periods of time at many different teperatures it just takes awhile to dial it all in. I would like to build a home made furnace but funds wont allow it.

Dude,

The more I think about it, the more I like the idea! It would be a lot cheaper to run than my electric oven. That sucker takes a couple hours to do the job. The first hour is just getting it up to 1800. The forge is minutes. If you could get the inside of the block (or brick I guess they're called) up to 1400 and stabilize at that temp. Hold for 10 minutes. Then slowly increase the temp to 1950 (depending on steel). Hold for 15 minutes you'd be there.

Hmmmm... trouble with my forge is the chamber is small and the flame would be right on the brick. That would make a hot spot - that wouldn't be good.

Steve
