What was the typical Fy for prestessing strands in 1958?

We’re doing some work at O’Hare and have the drawings, but they lack a lot of info.

 

Like Fy, for example.

 

Thanks!

For prelim. info, I'd use fy = 250 ksi, but I would definitely try to get a sample of the strand and get it tested before I'd rely on ANY value for "real design work."
