SpaceX Casting Raptor Engine Parts from Supersteel Alloys

• https://www.nextbigfuture.com by Brian Wang

Inconel is a family of austenitic nickel-chromium-based superalloys. Inconel alloys are heat and oxidation resistant materials. SpaceX is making its Raptor engine manifold out of Inconel.

nconel has been used for over 60 years in rockets and spaceplanes.

The skin of the X-15 Rocket-powered aircraft was made out of Inconel X. The X-15 first flew in 1959.

Inconel X-750 was used for the thrust chamber of F-1 rocket engine used in the first stage of the Saturn V.

The Space Shuttle used four Inconel studs to secure the solid rocket boosters to the launch platform, eight total studs supported the entire weight of the ready to fly Shuttle system.

SpaceX has used Inconel in the engine manifold of their Merlin rocket engine in the Falcon 9 and in the SpaceX SuperDraco rocket engine for the Dragon V2.
