Starship needs to be strong at cryogenic temperatures, and strong after being used as a heatshield to burn off energy from an interplanetary orbit. Both temperatures change the properties of the material it's made out of considerably. Is the same alloy really also the best at everyday -50 to 50 (c) temperatures?

Dunno but apparently it's used for that kind of stuff a bit https://www.upmet.com/products/stainless-steel/301
