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.
