Default Stainless Spring Bolts

I have a rusted solid bolt in the sleeve of one of my rear spring bushings, happens to be in the leading fixed end. These are normally I think SAE grade 8 or JIS 12.9 bolts.

Has anyone ever thought about using stainless? I know they use them on boat trailers that get dunked all the time but not sure stainless would be sufficiently strong on a vehicle.

One justification I can see is people often use greaseable bolts where are line bored and cross drilled. This takes away some material in the bolt, might be that removing 20% of the cross section of a grade 8 bolt is closer to a full cross section 316, which is similar to grade 5 in equivalency.
