Hot work tool steels

Hot work tool steels are alloyed tool steels for use in appli cations in which the surface temperature is generally above 200 °C. During the application the tool briefly comes into contact with hot material, the temperatures of which are well above 200 °C. Besides long term thermal load, there is the additional stress due to periodic change of temperature.
