Tool steels

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:

  • Air-hardening
  • Medium-alloy cold-work steels
  • High-carbon, high-chromium cold-work steels
  • Oil-hardening cold-work steels

Hot work steels are subdivided into:

  • Chromium
  • Tungsten
  • Molybdenum hot work steels

High-speed tool steels are divided into:

  • Molybdenum
  • Tungsten
  • Intermediate high-speed steels

Other types of tool steels include:

  • Water-hardening tool steels
  • Shock-resistant tool steels
  • Low-carbon tool steels
  • Low-alloy special purpose tool steels.
