Demonstrated by Elon Musk in the night of Friday Cybertruck Tesla got the stainless steel housing of cold rolled steel 301 class – exactly the same as that used in the construction exploded during tests the prototype vehicle Starship Mk1 from SpaceX.
"Skin is super-hard cold-rolled stainless steel alloy, which we have developed. We are going to use the same alloy in missile and Starship Cybertruck," said Elon Musk during demonstratie pickup the next day after an unsuccessful test Starship.
Thus, apparently SpaceX will not abandon the idea to use stainless steel to build space ships and continue their work on creating an interplanetary vehicle.
According to representatives of SpaceX, the test was the maximum pressure increase in the system, so there was a high probability that something will go wrong. The incident is not critical, as the company has previously decided not to use a Mk1 for the flight, and to focus on developing a Mk3 with an improved design. In addition, the Mk1 was not fully assembled, and the ship was missing the upper fairing and engines.
stainless steel according to Elon musk, good strength properties at both high and low temperatures. Not to mention the fact that she is almost 50 times cheaper than carbon fiber.
At the presentation of the pick-up Musk said that the stainless steel body is durable enough to withstand a bullet hit a nine-millimeter caliber. And demonstration with a strong blow "hammer of Thor" presentation Tesla Cybertruck really had very dignified.
