Best SS alloy to use in molten aluminum for skimmers and ladles
(OP)
I am looking for the best stainless steel alloy to use for molten aluminum alloy (380, 390 369)foundry tools. I would like to know why a particular alloy is more resistant to attack than others. How do the inconel alloys do in this application?

If you had a way to protect the stainless from contact with the aluminum, e.g. a coating, an austenitic would be the best choice since they retain their strength better at high temperature. 304 or 316 are common grades that would work. Inconel costs lots more and has the same drawbacks.
There is data on these grades at www.stainlesscenter.com
