I was making my first attempt to HT cpm154 when my oven declared an error at 1650 degrees as it was climbing to temperature.
I assume that it had reached the top of its temperature limit. I didnt know because I'm not sure of the operating limits.
I have a copper kiln by evenheat. It's an older oven.
If anyone knows the limits of this oven let me know.
The other thing is about the steel. What do I do now? Do I need to anneal the steel or what? I left the blade in the oven until it was completely cool allowing the temperature to come down nice and slow.
Any advice? Please?

If I had a clue, I would jump in, but I am sure some one will soon.

As Randy suggest go straight to the source. As far as your steel goes i would resume heat treat as normal when things are working properly.

Thanks guys...your right I should go to the manufacturer. I do believe it should go to 2200 though.

Let us know how it turns out.
I had the main circut breaker to my shop fail recently, I was in the middle of a 30 min. soak at hardening temp. on some D-2. It took me about 20 min. to diagnose and change out the breaker. When I turned the power back on the oven picked right back up where it left off, brought the temp. back up and then finished the remainder of the soak. I didn't know how things would turn out so I finished up with the normal tempering and when I tested the knife the results were the same as usual.
