ABSTRACT:
A steel which contains up to 0.15% carbon, 0.5 to 1.5% manganese, 0.03 to 0.10% silicon, 0.2 to 0.6% molybdenum, up to 0.05% aluminium, 0.03 to 0.05% titanium and 0.002 to 0.008% boron is particularly suitable as a welding consumable, for example as an electrode for the submerged arc welding of high strength micro-alloyed structural steels. Especially when used with a basic flux, welds can be produced showing excellent notch toughness characteristics which can even be improved by post-weld thermal treatments such as stress relieving and normalizing.
