RE: A325 Anchor rods?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The AISC Steel Design manual says that threaded rod meeting properties of A325 can be obtained by appropriate use of steel and quenching and tempering after fabrication. Could this be what the design engineer intends in this case?

We've called for and used A307 threaded anchor rod in retrofit work. I seem to recall a field engineer on one project telling me that the construction crews obtained A325 rod from the supplier and if it could substitute. 

Best regards,

A325 material are bolts with limited length.    If these are to be 
used as anchor material, the supplier probably won't be able to find 
A325 bolts long enough.
