RE: Grade 50 Steel Designation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
By the time you put in the caveats (supplementary requirements) necessary
for the A572 your better off using the A 992 spec.  That is what we are
doing.  It is what is being manufactured anyway.  And there is no price
differential.  It is the first time that a real carbon equivalent is
specified.  A992 is your friend.
