Any carbon steel or alloy that is particularly well suited to being produced into tools and tooling, such as cutting tools, dies, hand tools, knives, and other items, is referred to as “tool steel.” Their characteristic hardness, resistance to abrasion and deformation, and capacity to maintain a cutting edge at high temperatures are what make them suitable. Tool steels are, therefore suitable for shaping other materials through processes like cutting, machining, stamping, or forging.

Metals and other materials can be cut, pressed, extruded, and coined using tool steels. Their use in tooling is crucial; for example, injection molds need tool steels because of their resistance to abrasion, a crucial factor in mold longevity that allows for hundreds of thousands of molding operations over the course of a mold’s lifetime.

The most used system for classifying different tool steel grades is the AISI-SAE scale. A number is assigned to each alloy within a grade, such as A2, O1, etc.
