The lack of design rules limits the application of Very High Strength Steels (VHSS). One critical point limiting their use lies in their poorly documented low-temperature fracture properties in relation to more conventional steels. The two major concepts governing the assessment of steel construction codes are the Master Curve (MC) methodology and the T0 - TCV28J transition temperature correlation. Focusing on novel, directly quenched, high-performance steels, we investigated the applicability of the Master Curve methodology with special emphasis on the low-temperature region and checked the validity of the standard T0 -TCV28J transition temperature correlation. Improvements to the criteria are proposed for further consideration.
