Abstract: The paper deals with the assessment of the effect of content of cobalt and cryogenic treatment on mechanical properties and structure of Vanadis 23 and Vanadis 30 PM high-speed steels. The studied characteristics are evaluated after conventional heat treatment (quenching and multiple tempering) and also when deep cryogenic treatment at -196°C/4 hours was inserted between quenching and tempering. The mechanical properties are assessed by a three-point bending flexural test and by measurement of the hardness. Metallographic analysis is performed using an energy dispersive spectrometer (EDS) and the scanning electron microscope (SEM).
