Tool steel refers to a variety of carbon steel and alloy steel that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures. As a result, tool steels are suited for use in the shaping of other materials.
Cold-work steels are further subdivided into:
Hot work steels are subdivided into:
High-speed tool steels are divided into:
Other types of tool steels include:
