Hello and thank you for reading.
I'm looking for advice or experiences in selecting crucible material for molten magnesium. The crucible should be metalic and the current candidate material is stainless 446.
This is a lowish carbon, 26% Cr and no Ni metal. I understand that Ni is avoided because it reacts with Mg. Is there a better alloy than
446? Would more chromium mean better service life? I fear the crucible will become too brittle at higher chromium levels but maybe there are alloying ways around that.Any help or experiences are much appreciated.
