Anybody out there have experience turning Hastelloy? I just wasted 2 days trying to make a Hastelloy version of a 316 VAR part that I literally make by the 100,000s. Same exact dimensions out of 2 1/2" bar stock. Got different inserts, switched the few HSS drills needed to carbide, went by the manufacturers recommended speeds/ feeds. Id get 2 or 3 parts out of a a side of an insert, and then everything took a shit all at once. We're not even removing that much material. Turning, boring, drilling, od threading threadmilling, its all shit... Tore it down and went back to the usual stuff. Not sure what to do now.
