Tesla Cybertruck May Have A Rust Problem::One of the more standout qualities of the Tesla Cybertruck is its bare stainless-steel body. The stainless-steel body gives the Cybertruck a unique design, but

    They keep using the words “stainless steel” which is an alloy created to be rustproof by removing the iron out of it. So how exactly is this stainless steel if it rusts?

      I’m being pedantic here, but stainless steel still has iron in it. The addition of chromium forms an oxide layer on the surface that prevents rust. If the body is rusting, that means they used a shitty grade of stainless. Stainless with an appropriate amount of chromium (and nickel) is expensive as fuck.

        Stainless can go goofy after working it. Work hardening can even make stainless magnetic. Sorry, I don’t know the physics of why.

      Stainless has chromium added. Iron is still the main element. Different stainless steels have various other elements added, like molybdenum. There’s a wide range of SS for various purposes depending on their formability, weldability, corrosion resistance, heat treatment or precipitation hardened. Some are mildly magnetic (400 series), others not (300 series). Big range of cost too. Not sure which one they used. There’s also a finishing process called passivation that should be used to reduce the likelihood of corrosion.

      it rusts less, far less in fact, but it still does rust.

      Also there are different grades, i bet they cheaped out
