Limits of Sulfur in process stream for Inconel 617 1

[StressGuy]

I'm working on a application where, up until now, we were planning to go with Inconel 617 for a material due to the temperature (1200F) and nature of the process. However, previous to today, it was our understanding that there was no sulfur in the stream.

Now, we've been told that there is going to be around 20ppm of sulfur in the process that the Inconel will be exposed to. Is this concentration level of sulfur going to be a problem at 1200F? I've found lots of vague references to concerns with Nickel alloys in sulfur environments, but I've not been able to find much in the way of details.

Any answers or resources are appreciated.

Because of its aluminum and titanium additions, this version of inconel is well suited to resist sulfidation. If you want direct expert advice, go to nidi.org, and get a consultant's input for free.
