So I have to ask because I have been looking for a while and it doesn't seem to come up a lot. I have been doing as much reading as I can about metallurgy and heat treating. I specifically look at O-1, 1095, and W-2 because that is what I want to use.
Now.... I snagged a copy of the ASM Heat Treater's Guide book and looked over what other people do and I need some guidance and some people to lend me some understanding. You look at how to harden the steels, thermal cycles, temps, soak times, quench speeds, but!!!! you don't hear about some really small specifics. Like what does preheat entail, or what does preheat slowly to a specific temp mean? Like for D2 it says preheat slowly, or for O-1 it says preheat slowly, and preheat to 1200F. Does that mean you put the knife in the oven, turn the oven on, heat to 1200F, sit for a minute or two and then hit the HT temp and soak?
Also, you don't hear about how to use the ovens. Do you place the knives in while at room temp and then turn the oven on? Or do you hit the HT temp and then place the knives in?
I know these are weird questions but when you search for it I don't find much. Depending on the metal one way or the other could change your outcomes.
What you guys think?
