Hi,
I’m back after a bit of an absence, I guess life is at fault
.
I need some advice on the following please.
Long story short, 1095 kitchen style knife with hamon, came out of the quench with a bad “S” warp. Pretty sure I did not apply the clay at the same thickness and also one side was a bit lower than the other. I also made some variation from my original successful regiment, so a bunch of variables…bad.
Anyway, something to look into it later on.
For now, I didn’t want to ditch the blade or trying to fix it during tempering, didn’t look doable, so I decided to first re-anneal the blade and then take out the bends and redo it again.
Well, I have never annealed any steel, so I think it will be a good learning experience. I’m using an evenheat electric oven, so it should help with a full anneal, spheroidizing anneal, I believe it is called.
So, right now the blade is in the oven at 1375F. It will soak for a bit over an hour than ramp down to 850F at a rate of 50F/hour.
My question is, once at 850F, could I squeeze the blade in my stainless quench rig between aluminum plates and let it cool down to ambient from 850F down? I’m trying to get some of the warp out by squeezing it between the plates, then do the rest manually in a vice once in the annealed state.
So my main question is, cooling it a bit faster in the plates, from below 850F, will screw up the anneal?
Also, if you spot anything I’m doing wrong regarding the anneal regiment, please correct me.
Thanks in advance for your help,
Constantin
