The paper evaluates the properties of two cold work tool steels which differ in the production process and content of carbon and vanadium. Both steels are characterized by their great hardenability, toughness, dimensional stability and wear resistance. They are a subledeburitic steel X63CrMoV5-1 produced by classical metallurgy and a ledeburitic steel Vanadis 6 produced by powder metallurgy. Different austenitizing temperatures in the range of recommended values for the material were used during the heat treatment. Both materials were tempered at a temperature of 530 °C. Also cryogenic treatment at temperatures of −196 °C and −180 ° C for 5 h and/or 4 h was inserted into the conventional heat treatment cycle. The effect of the timing of cryogenic treatment in the heat treatment cycle was observed. Hardness measurement, a three-point bending test and a wear resistance test by the pin-on-disk method were used to specify the effect of the conditions of heat treatment on the properties of the investigated materials. |
