Tool Steels, or Takım Çelikleri in Turkish, are steels developed for the processing and shaping of various materials such as metal, plastic, and wood. Due to their chemical composition and properties, tool steels are more enriched compared to other steel groups. They are classified into non-alloy, alloy, and high-alloy tool steels based on their chemical composition. Additionally, they are categorized as hot work, cold work, plastic mold, and high-speed tool steels according to their application areas and working conditions.

Types of Tool Steels

Cold Work Tool Steels

Cold work tool steels are preferred in operations where materials are shaped at cold temperatures, with the temperature not exceeding 200°C during processing. They exhibit high initial hardness, which rapidly decreases when the temperature exceeds 200°C. Therefore, the operation is continued below this temperature. They are used in cutting and non-cutting forming processes. Some cold work tool steels according to DIN standards include: 1.2067, 1.2080, 1.2210, 1.2312, 1.2379, 1.2767, 1.2842, 1.2550, 1.2436.

Hot Work Tool Steels

Hot work tool steels are used in shaping iron and non-ferrous metals at temperatures ranging from 200°C to 600°C. These tools are part of the alloyed tool steel group enabling the shaping of materials through various methods such as injection, extrusion, forging, and cutting.

Some hot work tool steels according to DIN standards include: 1.2343, 1.2344, 1.2365, 1.2713, 1,2714.

High-Speed Tool Steels

High-speed tool steels are utilized in the production of cutting tools that can remove chips even at high cutting speeds. They retain their hardness at high temperatures for an extended period. Cutting tools for machines such as lathes and milling machines are often made from high-speed tool steels.

Some high-speed tool steels according to DIN standards include: 1.3343, 1.3243, 1.3207.
