An opinion is something like: "Stainless steel is a poor choice. It work hardens and becomes brittle"; but, in my case not a uninformed one.
I believe that the grade of SS (IIRC 301) tends to increase in tensile strength when work hardened, and also tends to "self heal".
So I read anyway, hopefully correct - as SpaceX is making rockets out of the same steel grade as claimed to what's going to be used for the production Cybertruck. Musk claims it costs US$3/kg.
