I'm not very well versed in metallurgy, but these cups are non-magnetic. I'm assuming this means they are Inconel, but I have no way to actually verify this. I was burned once once by a cheap eBay set... They were listed as GM NOS, but a magnet stuck right to them. Luckily I was able to return.
I'll try out the carbide first and see how they turn out. Thanks for the input!
