Depends on the temperature, time scale, amount of strain, heat treatment, etc.
The damping is inversely related to the modulus so that high modulus materials generally show the least damping. As a rule the 400 series has better damping characteristics than the 300 series.
The Japanese literature seems to have the best data for commercially available alloys.

Mike,
The specifics depend on what you are after. There are several damping mechanisms involved and generally frequency and strain dependent.
Internal rather than structural damping is always referenced in the materials literature.

You just have to hope that no-one wants to know the loss factor at 10 Hz or you would have to test a bar that was 250 metres long (for steel)! Although you could probably use bending modes instead of longitudinal modes at those frequencies as the radiation would be poor.
Call me cynical, but I can't believe that steel alloy manufacturers really go to such lengths, especially if all they do is quote a single figure at the end of the day.
OK, now I'm waffling. Past my bed time.
