The SpaceX Starship

The SpaceX Starship is indeed constructed primarily from stainless steel, specifically a variant known as 301 stainless steel. This material is chosen for its durability, strength, and ability to withstand extreme temperature variations during space travel. The stainless steel construction plays a crucial role in Starship's design, providing resistance to both the intense heat generated during re-entry into Earth's atmosphere and the frigid temperatures of space. This choice aligns with SpaceX's emphasis on reusability, as stainless steel can endure the stresses of multiple launches and landings.
