There are a lot of papers on the heat treating and corrosion testing of these alloys. = = = = = = = = = = = = = = = = = = = = P.E. Metallurgy, Plymouth Tube Upvote 0 Downvote

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. Upvote 0 Downvote
