In any case, high strength steels (like the kind they make aeroplanes
out of) don't have fatigue limits either.

Suggest you look at chart on page 5, looks like only 5-12% to me.

Steel only gets used for high stength or high vibration parts like
engine mounts, hinges and some anti frettage liners/facings. These
days more and more are made out of glue.

and on page 6 you will see R-R Trent 800 only has 25% steel. Shafts,
drives, bearings and a few bits of IP compressor.

Only the Russians use steel extensively.

and only USA Military can afford to make planes out of titanium like
SR-71.

I'm sure you're right that not many planes are made of steel these days.
All I meant to say was that those that are (or were) used cromoly tubing
which also doesn't have a fatigue limit.
