This report covers the research work carried out in developing a new low-cost, weldable steel, able to combine high levels of both strength and low temperature toughness in the temperature range +20 C to 100 C for thick components (50 mm - 125 mm). The study of the influence of low cost additions (B, Mn, V), combined with different amounts of conventional elements (Cr, Ni, Mo), on the properties has been carried out. According to the results of the experimental phases, a new composition was defined with reduced C and Ni concents, 1% Cr, 0.5% Mo, vanadium microalloying without boron. Special emphasis has been taken to obtain low levels of S, P and oxygen, as well as a strict control of residuals and inclusion morphology, in order to improve low temperature toughness. For the production of flash welded components, this new steel offers an optimized-cost alternative to other generic solutions which include important amounts of expensive additions (3% Ni, 1.5-1.5% Cr, etc) in their composition.
