The properties of steels cannot be determined solely by their chemical composition. Their final characteristics depend to a large extent on the applied processing methods - whether thermal, chemical, a combination of chemical and thermal, or thermomechanical treatment. When these processes are carried out properly, steels gain the required qualities and their durability is extended. This paper presents an overview of heat treatment techniques for tool steels. Understanding these principles is essential for the effective application of heat treatment and for minimizing the extent of subsequent finishing operations.
