SpaceX has shifted away from its previous reliance on 301 stainless steel for its Starship program. Company chief Elon Musk stated this week that SpaceX developed its own custom alloys specifically for Starship construction. This manufacturing pivot signifies a significant internal engineering undertaking by the aerospace firm.
The use of stainless steel has been a defining characteristic of Starship's design, chosen for its strength at cryogenic temperatures and relatively lower cost compared to other aerospace materials. The discontinuation of 301 suggests SpaceX has identified or engineered materials offering improved performance or cost-efficiency for the ambitious goals of rapid iteration and large-scale production. This change could impact the material science and manufacturing processes underlying future Starship development and production.
