I’m saying I don’t believe there’s any real strength benefits from adding large amounts of chromium and nickel. 316 (marine / medics grade) stainless has a yield stength if about 600Mpa, whereas high tensile carbon steels exceed that, and adding enough chromium to make corrosion resistant stainless steel makes it a pain in the bottom to work with. You don’t need to add all that expensive chromium (11%+) to obtain high strength steels. Dissimilar metals in contact with each other are a problem because they form a battery due to moisture and solutes, thereby causing electrolysis. This would be much less of an issue in the vacuum of space.
