D2 steel, also known as AISI D2 or tool steel grade D2, is a high-carbon, high-chromium tool steel. It is one of the most widely used and well-known tool steels, primarily due to its excellent combination of wear resistance, toughness, and overall performance in various applications. D2 steel is often used for making cutting tools, dies, punches, and other types of industrial tools where high wear resistance and good toughness are crucial.

Key characteristics and properties of D2 steel include:

1. Composition: D2 steel is characterized by its high carbon content (around 1.4-1.6%) and significant chromium content (around 11-13%). The combination of these elements contributes to its wear resistance, hardness, and corrosion resistance.

2. Hardness: D2 steel is known for its high hardness. It can be hardened to a very high degree, typically in the range of 58-62 HRC (Rockwell hardness scale). This hardness contributes to its ability to maintain a sharp cutting edge and resist wear.

3. Wear Resistance: D2 steel's high chromium content gives it excellent wear resistance, making it well-suited for applications involving abrasive materials, cutting, and forming.

4. Toughness: While D2 is not as tough as some other tool steels, it still possesses a reasonable level of toughness. This makes it suitable for applications that require both wear resistance and the ability to withstand impact or shock loading.

5. Corrosion Resistance: The chromium content in D2 steel provides a degree of corrosion resistance, though it's not as corrosion-resistant as stainless steels. Proper care and maintenance are still important to prevent rust and corrosion.

6. Heat Treatment: D2 steel requires proper heat treatment to achieve its desired properties. This typically involves processes like quenching and tempering to achieve the desired hardness and balance between hardness and toughness.

7. Machinability: D2 steel's high hardness can make it more challenging to machine and work with compared to lower-carbon steels. Proper tools and techniques are required for shaping and machining.
