I'm buying a cast carbon steel head and wanted to ask if anyone knew what was involved in heat treating it? Or do you know someone who could do it for me at (a very) reasonable price? Thanks guys.:D
 
your going to have to know what type of steel it is made out of first then do a google search for the facts on that steel. also ditch the casting, forged is where it's at. go to a yard sale / rendevoux / etc and pick up an antique forged axe/hawk head for cheap,

I've already bought it, so "ditching" it is not an option. The hawk head is made of 4140 carbon steel. I got this because I wanted to do it all (except the forging) myself. I just need some advise on how to do it from someone who is experienced in knife making/blacksmithing. Maybe I posted this in the wrong forum.
 
I dont care for 4140 for axes due to it's low hardenability 4150, 5160, L6, 1050, 1070 would have been much better due to the higher hardenabilty and edge retention. but hey have fun with your new axe. :D

Hardening 4140:: This alloy is hardened by heating to 1550 F and quenching in oil. It is best to normalize the alloy by heating at 1675 F for a long enough time to permit thorough heating, followed by air cooling, prior to the hardening treatment.

Tempering Temp Approx RC
(Fº) (2 hours x 2)

400º 42
500º 40
600º 38
