An extensive program of work to determine the HAZ toughness of line pipe and structural steels, containing up to 0.20% vanadium, with nitrogen in the range 0.005 to 0.018%, and niobium additions up to 0.05%, has been carried out using two-pass welds at 4.9 kJ/mm and multipass welds at 2 and 5 kJ/mm in both the as-welded and postweld heat treatment conditions. Using Charpy, CTOD, hardness measurement and metallographic examination, it has been demonstrated that in the as-welded condition substantial levels of vanadium can be tolerated with no adverse effect on HAZ toughness.
