I only have a slight clue if i hit the temperature during the normalization ;-)
I used the magnet to hit the ca. 1450 deg and then looked at the colour. I have a small colour chart i try to use as reference.

First cycle i try to hit about 1600 to 1650 and then slow cooldown in still air till i hit room temperature. 2nd cycle was just above nonmagnet to make grain smaller and then slow cooldown. 3rd cycle was to about 500 deg and then slow cooldown.
Thats just what i read at some point :-) Trying my best to recreate it.

I thought normalization did have a positive effect, but since the steel comes annealed and isn't forged, i see why its not necessary. Saves me a lot of time :-)
The blade did harden some and its much harder than the not heat treated areas, but with preassure i could still scratch the edge with a file.

I didn't know the steel stays nonmagnetic! Thanks for the heads up.
Time to do another HT, and if it doesnt work, break the blade to have a look. Luckily I'm not sure i like the design anyway, so this will be another test blade ;-)
