Hello, new to the forum, new to knife making, about 10 months.
If you have a problem with the heat treatment process can you repeat and still achieve the desired results? I'm heat treating A-2 steel. I placed then knife in the kiln, raised the temp AFAP to 1450 set to soak for 15 minutes. At 0 hold time the temperature starts to decrease to about 1420 then increases to the set 1450. This takes about 3 minutes. As programed, after the 15 minutes soak temp, raise AFAP to 1750. Set to soak for 30 minutes. At 0 hold time same thing happens. Get this resolved, go to take the blade out and it has fallen to the bottom of the kiln (vertical kiln). Cannot get to the knife without possibly burning myself. I have protective gear but I'm going to be safe. So I shut the kiln down.
The kiln looks like it has a problem and I made a mistake hanging the blade. But can I normalize the blade perform another heat treatment and have a usable blade.
Thanks, Joe
