Owners say they are noticing orange stains on the stainless steel panels of their new Cybertrucks.

Don’t give me that bullshit. If a kitchen sink that sees water every day doesn’t rust, neither should a $100K+ truck.
known as rustless steel
If they had picked the correct grade of stainless steel, it wouldn’t rust just by being outside. Cheaper grades rust, higher grades don’t.
Your kitchen sink isn’t exposed to the elements like a vehicle is. You ever seen stainless industrial sinks? They don’t always look so great after 10-20 years of abuse.
If these trucks are exposed to salt on the roads during winter weather they probably won’t fair well. Even stainless steel is prone to corrosion and ought to be painted or plated.
You’re comparing 10 years of rough abuse with metal being thrown into them constantly as well as all the acids and salts used in cooking against a year of just existing outside.
Edit: it’s not even a year outside…it was 2 days.
Do the ions from the salts form acids that react with the metal?
If I understand correctly (and I hope I do with a degree in chemistry), it’s moreso the long periods of exposure to wet environments. If those environments also include frequent exposure to salt it expediates the transfer of electrons to the outer surface of the stainless steel and causes oxidation.
Oxidation/rust/petina isn’t a bad thing. A thin outer layer of rust is sometimes used as an aesthetic preservative in architecture though. There are buildings that have heavy surface rust on them intentionally.
Probably not what you’d expect or desire on a vehicle, but very much possible. I wonder how the DeLorean DMC-12 held up in nasty conditions?
Put something rusty in contact with that sink for a little while and get back to us.
I have. I scrubbed the rust off with steel wool. As long as you don’t leave rusted iron against stainless steel for years, it’s fine. And that’s not what’s happening here.
So… you’ve experienced stainless rusting first hand and yet claim it doesn’t rust…?
Stainless rusts, fucking hell lmfao.
It doesn’t matter that it’s not what’s happening, it rusts. It’s that simple, any imperfection from salt or iron oxide (from rocks in asphalt) is a place for rust to start.
The stainless steel didn’t rust. The cast iron pan was accidentally left on the corner of the sink for a weekend with a little water under it. The rust wiped off very easily, because it was transfered from the iron into it, which is all that’s happening as long as it’s not left there for a significant amount of time.
The truck was driven in rain, with no snow or salt involved, and began rusting after 2 days. That’s a low grade of stainless steel to rust that fast.
