Stainless is quite stiff and springy so I suggest the same radius as the fingerboard or only slightly over bent . More is good with nickel frets though.
I think not all SS frets are created equal. Is there a way to quantify the quality, i.e. resilience against string wear? For example, I'm not impressed with the SS frets on my LTD but very happy with my Schecter Exotic. Both are MIK.
