Many years ago, I read Arthur C. Clarke's 1990 novel The Ghost from the Grand Banks which is about two teams trying to raise the Titanic.
I am aware that this title was also used as a chapter of Clarke's 1975 novel Imperial Earth, which I have never read.
I have subsequently found that the Titanic is used in the first episode/pilot of the 1966 Rendezvous With Tomorrow episode of The Time Tunnel TV show.
I have also identified that the Titanic is used in the 1961 I Heard You Calling Me episode of the fantasy/sci-fi series Way Out.
Does a sci-fi work from before 1961 exist that references the Titanic?
