I am working on an old horse shoe rasp making a Bowie. I annealed it @ 900 overnight and so far so good. I now have ground my blade and have to ht it, but find myself without a forge at the current time. So I am planning on popping it into my heat treat oven until it is non-magnetic and then do my quench.

I have successfully pulled this off with some friends damascus, but have not tried it with a rasp. Any suggestions on times and temps????

Before, I seem to remember about 5 minutes @ 1500-1600 would get the damascus to non-magnetic and everything worked fine.

Any suggestions would really be appreciated. It gets old having to wait on friends to fire up their forges, but I do enjoy the fellowship....but, yeah, I do need to get my own forge, I know...

Thanks in advance!

Since you don't know what the rasp is made of, you don't know what temp to use. About 50-100 above non-magnetic (1450-1500 range) and soak for 5 minutes is as good a guess as any.
