This paper is devoted to the ductile–brittle transition behavior of high strength low
alloyed (HSLA) structural steel NIOMOL 490K. The steel is designed for welded pressure
vessels exposed to dynamic loads, operating at temperatures below zero, and that is why it must
have acceptable toughness. Due to its importance for the safety assessment of pressure vessels,
a characterization of this steel with Charpy V-notch test in range of temperature between-60 oC
and +60 oC was undertaken. Ductile-to-brittle transition curves were generated in the present
study by using instrumented Charpy machine and V-notch specimens; notches were located in
the parent material, heat-affected zone and weld metal. NDT-temperature and tensile properties
in temperature range from -60 oC to +60 oC are presented in this paper. We used different test
temperatures to better understand ductile-to brittle transition response than just use either
Charpy energy or other related ductility criteria.
