A good piece on "Béton brut" or the return of Brutalism in design. Or rather lack of design. electrek.co/2019/11/24/the…

Musk uses 301 Stainless Steel. You see it on subway cars and trailers. It is austenitic low carbon non magnetic stainless with 7% Nickel and 17% 8% is the min amount of nickel added to 18% chromium to convert the ferrite to austenite. 301 is cheap and dissipates heat up to 1500F.
