Heat treatment

The problem with higher alloy steels is that temp and soak times are critical to getting everything in to solution. There's really nothing too fancy, just time and temperature....but I highly doubt you get it just right with a charcoal forge until you gain alot of experience.
1084/1080 is hypoeutectic, so carbon content is not over saturated, meaning you really only need to get to critical temp and quench. Don't need a long soak, and it's very forgiving.
5160 is also hypoeutectic.
1095 is hypereutectic, has more carbon than naturally wants to dissolve in the steel. Have to force it with specified soak temp and time.

Thanks, mesophilic That's some really helpful info! yeah, I started reading about the difficulties of soaking accurately without a gas forge. I Think ill try 5160... and maybe 1084 or 1080. Is there much of a difference between 1084 or 5160 from 1095s as far as edge retention and whatnot?

Your best bet is to fo online and look up Alpha Knife Supply they have heat treat for all of there steel listed, and if you buy steel I would recommend 80CRV2 or 1084 same steel different name. Remember yellow hot is too hot !

In your search engine type "5160 vs 1084" You should see some threads from bladeforums where they discuss alot of good info.
In my experience, 1084 gets sharper but 5160 is more impact resistant and keeps a working edge longer. Of course this will vary depending on the heat treatment and edge geometry. 1095 gets harder and sharper than 1084 but not as impact resistant as 5160, but again, depends on the factors.
My all time favorite is 52100, but that requires a professional level heat treatment.

Never knew their was so much to heat treating, I mostly use old files and just bring them up to non magnetic , quench , clean up and put them in the over on 375 for 2 hours, they seem to turn out nice. guess i may need to do a little more research , good info,thanks. :)
