As for Dilavar being non-magnetic. Carbon steel is in the ferrite phase and has a body center cubic (BCC) crystal structure at room temperature. At a temperature of about 750C carbon steel converts to the austenite phase with a face centered cubic (FCC) structure which is non-magnetic. Nickel is an austenitic stabilizer in steel. At about 8% Nickel and above, it suppresses the austenitic transformation temperture in steel to room temperature. So at 13% nickel, Dilavar is non-magnetic.

I noticed when I was drilling out studs, that the shavings are magnetic. This leads me to believe that there is some ferrite phase left.
