Super Duplex SS F53 S32750 vs F55 S32760
Super Duplex SS F53 S32750 vs F55 S32760
(OP)
What is the difference between these two grades, if any? And what could be the reason for picking one over the other?
As far as I could see, F55 has tungsten in its chemical composition.

There are a lot of papers on the heat treating and corrosion testing of these alloys.

If it is a new, and critical, application I personally would have greater faith in the validity of the Swedish-generated corrosion data for S32750.
