Great thanks for the clarification.
These all look great, but from looking at each alloy's spec sheet, most look like they have better corrosion resistance at lower temps. The 622, like you said, is pretty similar to the 625, so that's a possibility.
I was also told that stainless steel 441...
Awesome Thank you so much for the info! There has been welding on previous parts. They are usually milled, so yes, they are machined.
I'm not familiar with any of those alloys. They aren't all Inconel are they?
@EdStainless -
Sorry for the late response. I have still been investigating this. The research engineer before me had used this material before I started working here; I think that he experimented with Haynes 230 and Crofer 22 as well. My guess is that the INC 625 looked the best after hundreds...
Hi,
My company uses a lot of INC 625 superalloy for our fixture equipment in testing SOFC (Solid Oxide Fuel Cells), because of it's well know high temperature corrosion resistance (SOFC's typically operate at around 800C). This metal has been great for the most part, until recently...

Great question!
First off, what "high temperature" are you running the cell at? I assume somewhere in the range of 300C... that's roughly normal operating temps for PEMFC's if I remember correctly, but I could be wrong.
I work on SOFC's, and operating temperature is normally about 800C for...
