Anchor bolts of A320 steel
Anchor bolts of A320 steel
(OP)
This might be an obsolete topic about steel grade for anchor bolts.
In the current project, it is advised to use ASMT A320 Grade L7. Reason for that is for cold temperature application and high steel strength. But at the same time, the price to pay is the deeper embedment into concrete and possible ductility loss.
We used a lot of A307 anchor bolts before (also in cold temperature enviornment). Is there any adverse effect using A320? Thanks for comments.

Also, many suppliers make F1554 Gr 105 spec meet teh Charpy S5 spec for low temperature ductility. I would contact Portland Bolt. I believe they have a low temperature rated F1554 Gr 105 rod available.

You're right F1554 Gr 105 is about same strength as A320 Gr L7. F1554 Gr 55 (with Fy=55ksi) looks better for me if it suits old temperature as well.
