3. Thermal conductivity: 20℃≈26 W/(m-K), 400-600℃≈29-27 W/(m-K)
4. Specific heat capacity: 20 ℃ ≈ 419 J / (kg - K); with the rise in temperature increases gradually
5. Resistivity: 20℃ ≈419 nΩ-m, to 600℃ ≈922 nΩ-m

P18 Tool Steel Mechanical & Performance Properties

1. High hardness: After quenching (oil quenching at 1280℃), the hardness can reach 61-66  HRC. The higher the tempering temperature, the lower the hardness but the higher the toughness. Typically, it is about 65 HRC.
2. Excellent red hardness: It remains stable at high hardness up to 600℃, making it suitable for high-speed cutting environments.
3. Combining wear resistance and toughness: High tungsten and vanadium elements form hard carbides, which also have sufficient toughness to be suitable for impact environments.
4. Excellent thermal crack resistance: It has good thermal stability after heat treatment and outstanding crack resistance.

P18 Tool Steel Product Applications

1. Cutting tools: milling cutters, drills, taps, reamers, etc.
2. Precision tools: forming tools, gear shaping tools and tool blanks.
3. Cold working dies: used for stamping, cutting, punching and blade manufacturing.
4. High-temperature rolling and cutting applications: It performs exceptionally well in environments with high heat resistance requirements.
