Plates of low carbon steels with minimum yield strength of 450 Mpa for offshore constructions are usually produced by thermo-mechanical rolling or quenching and tempering. The yield strength requirements can be met using different concepts of chemical composition with variations in alloying and microalloying elements. The influence of such variations on HAZ toughness was investigated in this research programme. The chemical compositions of produced heats were monitored over a period of several months and appropriate heats were then selected. The target chemical composition was 0.07%C, 0.030%Si, 1.50%Mn and 0.50%Ni. Toughness tests were performed over a range of temperatures in order to characterize the transition from brittle fracture to ductile behaviour.
