You need Robbie Tunes or another Centurion expert to comment on this. Certainly the brand name is good quality and the model is one of their middle of the line bikes so it should be good for a 81 model. It's hard for me to say what tubing was used in 1981 because bike frames were upgraded continuously through the 80s. What was Hi-Ten in 1980 was a double butted chromoly frame by 1988 for some bike lines.
However, I do know this, my 1984 Centurion LeMans 12 is Tange 900, double butted chromoly steel, my 1987 is Tange 2. It would not surprise me to find that the 81 was at least chromoly main tubes.
