Cybertruck will be the last Tesla to use stainless steel exoskeleton

Yes, it is. Tesla went through numerous iterations of different metals for the skin and settled upon a slightly modified 304L (low carbon) stainless steel 1/4 to 1/2 hard (cold rolled). I don't think SpaceX has ever thoroughly explained all the engineering considerations used, but the material was not chosen accidently, it was chosen for it's favorable combination of properties.



It's not "coil rolling". it's "cold rolled". Cold rolling stainless alloys does more than harden the material, that's just one property change of many. It also densifies the surface making it more uniform and corroision resistant, with fewer microscopic voids, amongst other benefits.




The mechanical properties of the skin are very important for the overall structural robustness. Yes, that includes it's ability to maintain strength at high temperatures.



They are slightly different alloys, each tailored to requirements specific to each application. The Cybertruck has a higher chromium content for increased corrosion resistance. But as far as the world of stainless steel alloys go, they are quite similar.

Curious... do you understand work hardening ? Do you understand heat treatment, annealing, quenching, etc ? Do you understand fabrication steps such as straightening, or rolling ? Do you understand pressure vessel design ? Just curious...

I can go around in public proclaiming that I'm not going buy a Airbus A340 for private use because I don't like the CEO. That doesn't mean the price dropping suddenly is the result of my action.

Telsa is doing just fine. Millions of people around the world love these vehicles.

"Brand value" is not an objective metric that can be measured. Nothing more than biased speculation.

I knew that would be your response.

A+ Bravo!

All right guys, you can cut out early, @CyberGus already won the Internet for today! Better luck tomorrow.

I personally think the Cybertruck was a test bed to decrease the SS production cost for the starship and the air forming is a tool that will be co opted by spaceX. I have always envisioned a starship being canibalized on mars to build a Cybertruck as transport. Fanciful maybe, the kind of thought process of Elon? Absolutely. They use battery packs from cars to power the starship, why not.

You’re a very smart man and I know you know better than this.

All valuation is arbitrary. All the way down to gold. Zero people would argue this if they were trying to sell their brand and this very credible house said that they were worth X the only issue they might have is whether it’s more or less.

I own 70% of my business we had evaluated to calculate a value for shares. Zero people get to say oh that’s just imaginary.

We can’t call Elon the richest man in the world if we don’t make some subjective determinations about his worth because a lot of it is going to be just like Trump’s brand, subjective.

So, let’s not be absurd. Any valuation from Tesla from anyone is both speculative and subjective.

I knew that would be your response.

Yeah, and since I do love being right, thanks for dropping off these receipts! It’s just one of many data points that are out there that are pointing in the same direction.

I don’t generally feel the need to support my arguments in this setting with citations to generally available clearly non-controversial issues. People may not like that this is happening, but just about every signal out there says that it is. I’m always the first in line to call out FUD, passionately!

This is not that. Again, as Rumsfeld would say this is a “known, known.”

For the fingerprint OCD crowd, try Stainless Steel and More by Aqua Armor after you clean with Barkeepers Friend and Windex and then apply Stainless Steel and More after the surface had dried. Its a Stainless spray with Si02 ceramic coating that evens out the finish, reduces fingerprints.

This?

It’s my personal speculation but 4/5 CTs I see on the roads are usually wrapped. Personally I like the bare SS look but couldn’t put up with the fingerprints so mine is wrapped too despite wanting to keep it bare before purchase.

The fingerprint issue pushed my decision to wrap. There is a CT in my parking garage that had held out for several months. I noticed that it got wrapped this week (not as cool as mine though)

Elon Musk is hilarious, this is just to get people to quickly buy the Cybertruck. The Cybertruck exoskeleton will be in future Teslas as it’s the most cost effective and best structured ever produced. Elon has been tasked with a lot of jobs right now, once he’s done fixing other sectors he’ll come back and announce the Model 2 which will use this exoskeleton model. Just give it time, he’s a genius who cares for us.

Where did you get that it is based on 304L? Also, where did you come up with that it has a higher chromium content?

This is a joke, right?

Outside of battery pack size, the SS is the key driver in making the vehicle so expensive to produce, service, and maintain quality control.

The CT is far more expensive than Tesla thought it would be to produce and that's fine for us (we bought it), but how would saying the CT is the only vehicle now or planned for the future to use SS and airbending convince anyone to buy a CT? What sense does that make?
