Many stellite compounds can't really be cut, only ground or abraded. I use stellite 100 cutting tools in a lathe, and they're made to cut, not be cut.
Stellite contain iron, cobalt, chromium, mangan, carbon, molybdenum, etc.
depending on Head dia of the valve we have to set the Rotation of the valve, Stellite flow and Current
austenitic steel. Leading and trailing edges might have stellite added.
The only things unleaded gas could screw up in that engine are the valve seats. Volkswagen started putting Stellite (a very, very hard metal) seats in their engines in the 1960s, so you're fine.
In depends on the hardfacing technique and the final Fe dilution. Typical values range 42-45 HRC.
Currently any satellite must be launched on a rocket to reach space, though ideas for non-rocket launch exist.

Did you mean a stellite TV, phone or navigation system? The answer will depend on what type of satellite service you are looking for. If its satellite TV id first make sure you can get service in your area.
If it's got the original valve seats in it, I'd recommend using Lead Substitute in your gas. If you've got stellite valve seats, which by now you almost certainly do, unleaded is fine.
The most popular metal for cutlery is steel, an iron based alloy. Also, rarer alloys such as Stellite, Talonite - Cobalt based alloys, and Titanium based alloys. The list of steels and other alloys used in knifemaking is attached.
We're not sure what the first launch may have been, or how many attempts precededthe first success. But the first object to successfully achieve Earth orbit was Sputnik-1,launched from the Baikonur Cosmodrome in Kazakhstan on October 4, 1957.
