Comment on Tesla Cybertruck May Have A Rust Problem
givesomefucks@lemmy.world 9 months ago
One way to keep the Cybertruck’s stainless steel body from rust and damage is to get it wrapped. Interestingly enough, while Tesla saved some money by not clear coating the truck’s body, the automaker offers a “Satin Clear Paint Film” and a “Color Paint Film” for the Cybertruck that costs $5,000 and $6,000. The “self-healing, urethane-based film” protects the truck from scratches and corrosive substances. After hearing about the issues that current owners are having with rust and corrosion on their trucks, we’d consider the film to be a must-have for Cybertruck owners.
There’s a fix, it just cost 6k…

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?
There are different types of stainless steel. Remember kids, it’s stain less not stain never.
I guess there is still iron in it. Looks like they didn’t use an alloy with enough chromium for the application.
Tesla, cutting corners?! Say it isn’t so!
Well it has to be workable/formable, weldable and crack resistant under stress. Just welding most stainless mess with its ferrous properties.
In addition to funny is this also actually true?
Absolutely. Why would they call it less if it’s actually never? That would be exceptionally terrible marketing.
Yeah. I have a small pocket knife i carry everywhere, it is stainless. I’ve had it for years, and typically bring it in the water with me clipped to my swim suit (incase i need to cut a tangled rope). I wash it like a dish with soap and water, i use it hard and put it away wet, and it has been fine for years and years.
After all this, i took it on a single trip in salt water, it spotted with rust that night.
I also have a sig938 sas which has a stainless slide. I keep that dry and oil it on occasion, and yet that one spotted with rust within a year despite me taking good care of it.
Different grades of stainless make it different grades of rust resistant. Kind of like calling IP67 electronics like the iPhone 7 “waterproof” when they can only really withstand splashing
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. Not sure which one they used.
You are absolutely right, just for clarity:
Chromium needs to be > 12 weight-%. If you take 18 w-% Cr and 8 w-% Ni you get an austenitic steel which is (normally) neither magnetic nor able to be hardened.
it rusts less, far less in fact, but it still does rust.
The answer is in the name. It’s stainless not stainproof
