Tools Steel

Tool steels encompass a diverse range of carbon and alloy steels renowned for their exceptional wear resistance, making them indispensable for crafting tools used in various metalworking operations such as forming, cutting, machining and casting. From dies and files to punches, burs, chisels, shears, blades, molds, and more, they serve a multitude of purposes.

Traditionally, tool steels are categorized into seven primary groups :

  • Water-hardening steels (Type W: Water hardening) : For cold work (low-alloyed).
  • Shock-resistant steels (Type S: Shock-Resistant) : Combining resilience to shocks with moderate wear resistance.
  • Cold-working steels (Types O, A, D) : Suited for temperatures below 250°C (500°F), differentiated by their hardening methods.
  • Hot-working steels (Type H) : Designed for high-temperature applications ranging from 300-600°C (600-1200°F).
  • High-speed steel (HSS) : Highly alloyed steels for machining tools unduring temperatures up to 600°C, with variants like T (Tungsten) and M (Molybdenum). 
  • Mold steels (Type P) : Ideal for mold used in die casting zinc and plastic injection, characterized by good machinability and polishability.
  • Other low-alloy steels intended for a particular purposes (Type L).

The selection of the steel group and type hinges primarily on the intended use of the tool, dictating the optimal characteristics required for its longevity. This decision is influenced by various factors, including tensile strength, hardness, service temperature, thermal fatigue, toughness and dimensional stability.
