It's a 30X series stainless steel with extra chromium added for additional corrosion resistance. The magnetism is a function of the austenitic steel being converted to martensitic stainless steel by a custom machine the steel is rolled through to make it harder and more damage resistant. This doesn't change the alloy, it changes the structure of the alloy, the atomic structure becomes tighter and more crystalline on an atomic level. That is why the engineers at Tesla christened it "HFS" or "Hard F*ckin' Steel". Austenitic stainless goes from non-magnetic to mildly magnetic as it is work hardened.Well, that settles it. This is not even a 300 series SS, with it being 400, it makes it even more difficult to maintain it. I wouldn't be surprised if these things turn really ugly after a couple of years, at least without a lot of elbow grease.
Isn't metallurgy great? I wouldn't worry about corrosion with the tighter grain structure and added chromium to create a stronger passivity layer. There is no evidence it has a corrosion problem (unless you are particularly gullible).
