The first industrial application of elevated and high-strength steel in the form of hot-rolled strips and sheets
was the manufacture of pipes and vessels under pressure, as it was possible to reduce the thickness, i.e. to
reduce the weightof welded structures. The high-strength low-alloy steels used today are usually obtained by
suitable chemical composition and thermomechanical treatment.
Our investigated steel NIOMOL 490 K belongs to the class of molybdenum microalloyed steels, where the
microalloying with molybdenum serves to increase the heat resistance of the steel and at the same time
strengthen the influence of other alloying elements. This steel grade is designed for the manufacture of welded
pressure vessels fabrication and is mainly used for dynamic loading conditions at low operating temperatures.
In the present paper, the tensile and hardness tests were used to determine the effects of alloying elements
on the mechanical properties of NIOMOL 490K steel in the tempe...rature range from -60°C to +60°C.
