This paper is dedicated to the ductile–brittle transition behaviour of the microalloyed structural steel NIOMOL 490 K. This steel grade is used for welded pressure vessels subjected to dynamic loads and operating at sub-zero temperatures. Therefore, it must have an acceptable toughness. Due to its importance for the safety assessment of pressure vessels, a characterization of this steel was carried out using the Charpy V-notch impact test in the temperature range between - 60 ◦C and + 60 ◦C. The notches were located in parent material, heat affected zone
and weld metal. In this paper, the tensile strength properties at ambient temperature and the nil ductility temperature in the temperature range from - 60 ◦C to + 60 ◦C are presented.
