D3 is a high carbon high chromium tool steel, known for its wear resistance and dimensional stability after hardening. After heat treatment, D3 has high hardness, good wear resistance, and high dimensional stability, making it not easy to shrink during processing. Moreover, D3 also has a certain degree of hardenability. Generally speaking, D3 tool steel is similar to D2 tool steel, but it is important to note that D3's wear resistance is superior to D2, making it more suitable for manufacturing cutting tools and other components. Due to its higher wear resistance, the machining difficulty of D3 tool steel is higher than that of D2.
