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

There are different qualities 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.

Forming it screws it up too. Work hardening after forging can make it magnetic.

In addition to funny is this also actually true?

Yeah. I have a small pocket knife i carry everywhere, it is stainless. I've had it for years, and frequently 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 Sig P938 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. Luckily sig replaced the slide but this taught me one good lesson.

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. Some can get dunked, some can't.

Absolutely. Why would they call it less if it's actually never? That would be exceptionally terrible marketing.

[–] lars@lemmy.sdf.org 9 points 9 months ago (2 children)

Sure, “less” means “fewer” or “not as much as”.

But the suffix “-less” means “without”:

flawless: no flaws
spotless: no spots; clean
fearless: without fear

[–] Peppycito@sh.itjust.works 3 points 9 months ago

So then it's genius marketing. Stainless absolutely stains and rusts.

Reckless: without wrecks

Nah, that’s without Rekts.
