Does anyone know what this is used for? Or even likely what grade stainless it could be? I inherited a handful of these shorter pieces and a longer length, that I'm sure is going to be useful for something someday...
This is a stainless steel ____________.

Stiffener bracket of some sort?

It depends what you mean by "higher grade". If you consider the 400 series stainlesses, some of them especially strong and often used for knives, to be higher grade than the 300 series, well, some 400s are magnetic, while 316 isn't (304 isn't either unless you cold work it).

Yep, test the magnet a couple of other things and see if the pull is similar or a lot less.
Cut a small piece and leave it outside to see if it rusts.

No rust what so ever from being outside and non magnetic. When clean, it appears somewhat polished. It's heavy and stiff. My first thought that it was a special raceway to protect something. It wouldn't hold a lot of volume on its own. I thought that maybe someone who worked in an industrial environment may know. Maybe conduit / high pressure hose near a control station?

Probably 300 series then, maybe even 316 if it has been heavily exposed with no rust at all. It isn't some sort of standard product I have ever seen but more likely something someeone had made for a task like others have noted. Stiffener or raceway or the like.
400 series are slightly magnetic and also are considered tool steel. We make a lot of injection molds from 420, and I assure you it is not a "lesser grade" as it is very high strength and hardenable.

Perhaps you could form a shield to keep scum from quickly stealing your Cat.
