Rocket booster temperatures won’t go much above 600 Kelvin on hottest parts of main body & maybe around 1200K on base, which uncooled steel can handle. Starship is around 1700K for a Mach 25 entry, so needs shielding of some kind.

Technically, the steel is radiatively cooled (not uncooled). T^4 is one of the most interesting things about reality!
