Posting from a cell phone so, I apologize for any weirdness.
Working with a 60x18 interior, Olympic Kiln with a Gensis 2.0.
Quench oil is "Fuchs Thermisol K9 with Quenzine", this was chosen by my boss, I'm only familiar with Parks.
We have a decent hardness tester, not lab quality by any means.
I have a couple questions regarding heat treating complete bars of 5160. I have experience and less issues with doing knives and sword blanks, but for the sake of production, preheat-treated are faster.
3x48x.24 bars harden with a 15 minute soak at 1500, then ramp to 1550 in the kiln, before quench. Anything less, and I'm not getting much over 60HRC. Does this seem normal?
I assume that the heat loss is why I need to be higher before quenching. Paying attention to the color seems to confirm this.
The main question is, following the same procedure, why is the 1.5x48x.375 bar not hardening completely?
My knowledge and experience from this forum 17 years ago is how I got to where I am now, making swords, knives, heat treating, and designing production items for a company that makes fencing swords. So I thank you all for your input, then and now.
