Selection of steels and coatings for cold-work tools

Selection of tool steel grades and PVD coatings is of key importance for the tool longevity. Therefore, it is very important to recognize all present wear mechanisms in tool operation and select the most influential one, which enables proper selection of the tool steel grade for the active tool positions. The case study of certain tool steel selections has been provided, along with presentation of the exploitational behaviour of PVD coatings in certain cases. The feedback received from exploitation of tools is included.
