Tools made of hot-work tool steel
Hot work steel has a broad field of application. Tools made from this material are used in numerous applications.
Hot work steel is employed to shape workpieces made of iron, non-ferrous metals, and their alloys at high temperatures without causing any chip formation. It is used in processes such as die casting, extrusion, and drop forging, as well as in the production of pipes and glass. Hot work steel is exposed to temperatures of more than 200 °C during its use, and no structural changes should occur. Therefore, the structure of the material must be sufficiently stable and resistant to tempering.
Tools made from hot work steel are subject to varying thermal loads, occurring at the contact surfaces of the tool with the material being processed. To ensure durability, a sufficiently stable structure of the steel is crucial.
The thermal load, combined with wear caused by abrasion or impact, requires specific properties from hot work steel. These include high tempering resistance, temperature cycling resistance, heat resistance, thermal toughness, and wear resistance. The use of high-quality hot work steel is crucial to ensure high efficiency and productivity in later production stages.
