Marketing hyperbole, mythology, and opinions are of interest, but one cannot argue with numbers; which we have thanks to Dave Suponski and Ron Graham

Scroll down about 3/4 here for the actual composition analysis
https://docs.google.com/document/d/1...EK8OtPYVA/edit

Titanic, post-WWI Vulcan, and Trojan were essentially the same; AISI 1030 and 1035 Medium Carbon steels.
Titanic had low levels of both nickel and chromium compared to the others.
Parker Steel was non-standard Acid Bessemer Resulphurized Rephosphorized AISI 1109 low carbon Steel.

Of course composition could vary somewhat based on years of production ie. pre-WWI and post-WWI

As to the sources of "rough forged tubes", this should be of interest

If someone would like to send me a chunk of their Acme or Whitworth barrels I'd be happy to run the specimen over to METL for testing
