Making a hawk-

heat treat and tempering rages?

Can't find one of the scrap lists that has metal types- tired of looking and searching.

Thanks

Probably a medium carbon steel. Check sparks against other steels. What do you want to use it for?  Throwing hawks will be softer than hatchet used hawks. Generally if I don't know the alloy I'll try warm vegetable oil, remove any decarb layer and check if it's hard enough for my taste.  If not go to something like a quick oil, Parks 50 say, or even a brine. The faster the quench the greater the likelihood of catastrophic failure.
