Cold-work tool steels based on Cr-V alloying belong to the most important toolmaterials for large series manufacturing. To enable high production stability, the tools must withstand various types of degradation processes, concerning firstly plastic deformation and wear. Therefore, the materials should have a high hardness, tensile and/or compressive strength and wear resistance. On the other hand, the materials have to resist brittle fracture, e.g., they must exhibit sufficiently high impact toughness and fracture toughness. This paper deals with an overview of the heat-treatment procedures and surface engineering techniques suitable for Cr-V tool steels. The effect of each of them on the main mechanical properties is also demonstrated and discussed. As a typical example, P/M made from the Cr-V ledeburitic steel Vanadis 6 is presented.
