I had my first attempt at plate quenching stainless last week. It didn't go to plan, but I didn't realize until after tempering. I didn't get the temp down quick enough after soaking in the heat treat oven.
Can I re heat treat it again or am i screwed?!
I was using Sandvik 14C28N.
I've had AEB-L warp so bad that I had to completely redo the heat treat on it. I did a nice long anneal on it then redid the entire heat treat and cryo on it. Blade hardened up and finished out without issue. The trick will be doing the proper anneal on it. Worth a shot. If it doesn't work, then you're just right back where you started.
Thanks JH, will give it a go
As JH said, I haven't seen any issues with re-heat treating metals, except for some of the powdered steels. a nice long soak to get everything back into solution should be the trick, but too long and you will get bad grain growth. Remember to always test your process on a spare chunk of steel.
