Formula One, NASCAR, NHRA, and APR, LLC exhaust systems. It is also used in the turbo system of the 3rd generation Mazda RX7, and the exhaust systems of high powered Wankel engined Norton motorcycles where exhaust temperatures reach more than . Inconel is increasingly used in the boilers of waste incinerators. The Joint European Torus and DIII-D tokamaks' vacuum vessels are made of Inconel. Inconel 718 is commonly used for cryogenic storage tanks, downhole shafts, wellhead parts, and in the aerospace industry -- where it has become a prime candidate material for constructing heat resistant turbines. Aerospace 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. Eight frangible nuts are encased on the outside of the solid rocket boosters, at launch explosives separated the nuts releasing the Shuttle from its launch platform. North American Aviation constructed the skin of the North American X-15 Rocket-powered aircraft out of Inconel X/750 alloy. Rocketdyne used Inconel X-750 for the thrust chamber of the F-1 rocket engine used in the first stage of the Saturn V booster. SpaceX uses inconel (Inconel 718) in the engine manifold of their Merlin engine which powers the Falcon 9 launch vehicle. In a first for 3D printing, the SpaceX SuperDraco rocket engine that provides launch escape system for the Dragon V2 crew-carrying space capsule is fully printed. In particular, the engine combustion chamber is printed of Inconel using a process of direct metal laser sintering, and operates at very high temperature and a chamber pressure of . SpaceX cast the Raptor rocket engine manifolds from SX300, later SX500, which are monocrystal nickel alloy (improvement over older Inconel alloys). Automotive Tesla is now claiming to use Inconel in place of steel in the main battery pack contactor of its Model S so that it remains springy under the heat of heavy current. Tesla claims that this allows these upgraded vehicles to safely increase the maximum pack output from 1300 to 1500 amperes, allowing for an increase in power output (acceleration) Tesla refers to as "Ludicrous Mode". Ford Motor Company is using Inconel to make the turbine wheel in the turbocharger of its EcoBlue diesel engines introduced in 2016. The exhaust valves on NHRA Top Fuel and Funny Car drag racing engines are often made of Inconel. Inconel
