SpaceX develops custom alloys for Starship, stops using 301 stainless steel
Elon Musk confirmed that SpaceX has developed its own alloys for Starship construction, discontinuing the use of 301 stainless steel. This change represents an evolution in the materials used, beyond the initial shift to stainless steel for the spacecraft. The creation of these custom alloys aims to optimize specific mechanical and thermal properties required for Starship, although Musk did not disclose exact compositions or specific technical improvements achieved.
- SpaceX stopped using 301 stainless steel in Starship
- Custom alloys were developed for the spacecraft
🔎 Why it matters: Starship's material version changes with proprietary alloys, not just 301 steel.
📈 Upside: Potential improvement in specific mechanical and thermal properties for Starship.
📉 Risk: Technical details and public validations of the new alloys are unknown.
