I was wondering if anyone can tell me what the composition of the Saturn V's F-1 engine's nozzles are? I have looked online and they have many different statistics but I cannot find out what they were made of, can anyone help?
The F-1 Engine Fact Sheet states that the "nozzle extension" (the part of the nozzle below the turbine exhaust manifold) was made of high strength stainless steel.
The "thrust chamber", including the portion of the nozzle above the turbine exhaust manifold, was formed from tubes constructed of Inconel X-750, a high-temperature, heat-treatable, nickel base alloy. (reference)
