What is d2 steel?

D2 steel is a high carbon, high chromium tool steel known for its excellent wear resistance and edge retention. It is often used in industrial applications, such as cutting tools, blades, and dies.

D2 steel contains around 1.5% carbon, 1% chromium, 0.6% molybdenum, and small amounts of vanadium and tungsten. This composition gives D2 steel its high hardness and toughness, making it suitable for demanding applications.

D2 steel can be hardened to a Rockwell hardness of 58-62, making it significantly harder than most stainless steels. It also has good corrosion resistance and can maintain a sharp edge for an extended period of time.

However, D2 steel can be difficult to work with due to its high hardness and wear resistance. It requires proper heat treatment to achieve optimal performance and can be challenging to sharpen.

Overall, D2 steel is a popular choice for applications that require a high level of wear resistance and edge retention, such as cutting tools, knives, and industrial equipment.
