Sažetak

Tool steels for hot work are designed for tools, which are heated during operation to a temperature higher than 200 °C. In such conditions, this group of tool steels is exposed to sudden temperature changes, high mechanical and impact loads, so extremely good properties are required from tool steels for hot work. Tool steels are alloyed with carbide forming elements (Typically: vanadium, tungsten, molybdenum and chromium). Addition of alloying elements serves primarily purpose to improve the hardenabillity and to provide harder and thermally more stable carbides than cementite. Assuming proper heat treatment, the properties of a tool steel strongly depends on which alloying elements are added and their respective concentrations.
