Here's some info from this web site:

Note that the strength is 9800 lbs - this is usually breaking strength. I 
don't know what you are using this for, but some codes require a factor 
safety of 5 of the Fu.  (whoops - just found a NAVFAC document that allows 
a FS of 2 for unoccupied areas) <> 

I actually started looking at sailboat rigging as my own data base didn't 
have much to offer.  I do have a John A. Roebling catalog - circa 1957 and 
it has a B.C. of 8000 lbs.

I'm also looking at ASTM A475 and notice that there are different grade os 
wire, i.e. Utilities grade, common grade, Siemens-Martin grade and high 
strength grade.   Also note that you can get the wire prestretched.
