Corrosion resistance of Inconel 718, Inconel X750 and Incoloy A286 with dilute sulphuric acid at 70C

I am aware that these three metals are not great with sulphuric acid, but I need to specify a spring material that will work in this application. I picked what I consider to be probably the best choices, but if anyone can give me some insight in to which would be the best material to use, I'd appreciate it.

How dilute?
Have you gone to the Special Metals web site and looked at the data sheets for these alloys?

Does the spring need to be metal?
