Wet intergranular corrosion and single crystal cast alloys?

[Feldmann359]

Hello!

Does anybody know if it would help to use a single crystal alloy if I have problems with wet intergranular corrosion?

No grain boundaries, no chromium depletion at the grain, no possible attack?

Or is it not as simple as I am thinking?

Thanks for your comments in advance!

If your part could be made from SC material it would help.
But it would be easier to select the correct alloy and heat treatment to avoid the problem all together.
