Heat treating 17-7PH stainless in a mini melting furnace?
(OP)
I have some stainless steel 17-7 PH that is currently in condition C. So now I need to heat it to condition CH. I'm wondering if I could use one of the mini melting furnaces noted below. The part will fit in there, the furnace is cheap and I only need a few parts. The 17-7 needs 900 degrees F for 1 hour so I think in theory this will work. My concern is that flatness will be compromised or it'll age unevenly. Is this a good idea or bad idea? I've not tried to heat PH stainless before and I'm not sure what would be cheap and effective. Regards. Ant.

You need a small box furnace.

Though you could use a lower temp rated one.
A Blue M or Thermcraft would be just right.

You should be able to find a commercial heat treater that has small furnaces that could very well be cheaper than that little furnace. That's what I would do.

Now, if you are going to do this every week - that changes the equation a bit!!
Don't forget the cost of running this "little" oven or any mistakes you might make!!

Would it make any difference using a mini kiln? I've seen one that is small and could be sent by courier.

These are popular with knife makers and other hobbyists.
A small kiln might work, but you need to run a few trials to get the temp settings worked out.
