1084 stock removal heat treating

[Ghankins]

Hi everyone. Im a green horn at this fascinating journey of knife making. Been at it about 7 months and really feel I've found my passion. Absolutely love it but have some heat treat questions
Im moving up from my 2 brick forge to a kiln and curios about normalizing/thermo cycling benefits with stock removal blades after profiling and grinding bevels prior to final heat treat.
Opinions on water quench between tempering cycles also. Currently working with 1084 and 8670.
Thanks to all

curios about normalizing/thermo cycling benefits with stock removal blades...

I think this depends on the source of your steel. Some steels come normalized/annealed and won't need any thermal cycling/grain refinement when doing stock removal.

If you're talking about cooling the blades with water between multiple tempering cycles, no problem there, at least with those steels. I do it all the time.

The steel is from Pops knife supply. Got several knives out being used by customers and so far they are pleased. I've been happy with my on personal knife. These are all from my simple single burner 2 brick forge quenched in 125 degree canola oil tempered 2 x 2hr cycles at 400
Thank you

Read Larrin's latest article on Thermal cycling. It has all the info needed for stock removal HT. His book is invaluable, and I highly recommend it.

I can say the 8670 from Pops does not need thermal cycled if doing stock removal, it’s grain is pretty fine from the mill with proper hardening temps, I’ve made quite a few knives from it and it works great, best bet with steel is to ask the supplier for each grade and if unsure try hardening a sample and breaking it to check grain.

Thanks for the information
