Customer requires high toughness in lowered temperatures, guaranteed weldability and also relatively high yield strength. Applied heat of steel has 0,1 of carbon content and 1,5 percent of manganese. Conventional alloying with conventional heat treatment not always leads to consistency in mechanical properties. Application of usual heat treatment (quenching and subsequent tempering) ensures only close compliance of requirements in yield strength. Toughness at -46\u00B0C (minimum 45 KV) is usually 20 to 120 KV (considering the transition area), therefore it is very complicated to meet these requirements and ensure the reproducibility of the results by applying conventional heat treatment. New heats with combination of several microalloying elements (Ti, V, Nb, Zr ) and theirs amount were prepared. Physical simulation of forging on real specimens was done on unique device with possibilities of temperature and deformation controlling. The main goal of this experiment was to assess mechanical and microstructural properties of steel after addition of various amounts of various microalloying elements." . . .
