Corrosion resistance of Hastelloy W

[kevlar49]

Does anyone have information regarding the corrosion resistance of Hastelloy W?

We are looking to subsitute it for Hastelloy C-276 tie wire for an application in a Naphtha reformer, so the primary corrodent would be hydrochloric acid.
Operating temperature can be around 250°F.

"W"? The cast grade?
Have you looked at 625 or C-22? the onlyl other two alloys that I think of for a severly reducing environment are B-2 and Ultimet, but they will both be more money. Though I shouldn't say that about Ultimet, Co and Ni prices are almost the same today.
