Abstract


High tensile, microalloyed steels, such as 450 EMZ design steels which are studied in this article, are used in offshore platforms and other structures subject to extreme working conditions, requiring high resilience and fracture toughness at low temperatures. These steels have been subject to a control in their welding parameters to obtain a low heat input which allows for the maintenance of correct toughness values in their heat affected zone (HAZ). The present article analyses the values of hardness, resilience and toughness, as well as the points of greatest brittleness of the HAZ (1).
