The article presents results of the study on mechanical properties of a new hypereutectoid Mn-Cr-Mo-V steel. Mechanical tests comprised tensile test, impact toughness test and hardness measurements. Moreover, the kinetics of phase transformations of undercooled austenite by continuous cooling and the kinetics of phase transformations during heating from the quenched state (tempering) of this steel was analyzed from dilatometric tests. It has been demonstrated that the new steel, after applying of a proper heat treatment, poseses properties (especially the hardness) which meet expectations of industrial community with regard to tools used in hot and cold working. It is anticipated to use this steel for manufacturing of case-hardened tools.
