Mild steels
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.
