toughcore® steels are characterized by outstanding toughness (CVN, CTOD and Battelle) to the core, even at very low temperatures and for the largest plate thicknesses. Based on the significantly lower transition temperature of ductile to brittle fracture, applications can be achieved with substantially lower risk of brittle fracture. Even the heat-affected zone (HAZ) of welded structures features improved toughness to ensure the highest safety standards.
