T200X compatiblity with 2205

[holdpt]

I debated on what forum to use for this so I hope I have chosen correctly. We have had success with overlaying T200x on A36 but have a scrubber job calling out 2205 whereas the customer wants the T200x overlay performed. In talking with the TX distributor of the overlay material, we were informed that they do not have specifics on compatibility of such a combination. Does anyone have information if this combination has/can be acceptably performed?

Thank you.

The problem with weld overlay on 2205 is the risk of forming detrimental secondary phases in the duplex during the process.
These phases will significantly lower the corrosion resistance of the 2205.

Why on earth do they want to overlay it?
2205 is much stronger and more wear resistant than almost any other alloy.

Never seen it used in a scrubber like you have stated. I would not recommend it.

Thank you gentlemen for the comments. I checked again with sales to be certain that 2205 was called out and it appears that the customer may be reversing their decision.
