WELDING NIOBIUM BEARING HSLA STEELS ‘MYTHS AND MAGIC’
Niobium is not currently added to ferritic steels with the specific objective of improving weldability and is more likely to be present to harness its combined beneficial effects on strength and toughness.Nevertheless,as carbon levels in many classes of HSLA steel,are progressively reduced,there is an increasing awareness that,amongst the microalloying elements,niobium is uniquely placed to deliver the mechanical property combinations that modern specifications demand and simultaneously deliver a ”bonus” by way of enhanced weldability.
