Have tried to harden pieces of very old plow disc by quenching in oil, and also water, and it doesn’t seem to harden. I got it to non-magnetic before each attempted quench. I did NOT normalize 3 times before the quench, and I did NOT soak before the quench. Is it worth it to keep trying by adding those steps before I harden? Or is steel just not able to be hardened? Thanks!

Working on my first Osage self bow. The stave has a lot of thick rings. In a few places I have nicked just the very top surface of my chosen ring, but these nicks are nowhere near going through the whole ring. Are these minor nicks an issue? Thank you for your help
