Look at portlandbolt.com. They have a lot of good information to make the comparisons between most grades you are looking for.

Depending on diameter and application, F1554 Grade 105 (above 1" diameter) or A449 (up to and including 1" diameter) would be closer equivalents. Here is the specific FAQ that addresses it from Portland Bolt's website:

Be careful. Even if they appear to have the same or identical strength, if they do not meet ASTM, they may or may not be held to the same requirements in terms of quality, inspection, testing, elongation, etc.
