About the Steel
1.2379 / D2 Tool Steel is a high-carbon, high-chromium cold work tool steel known for its exceptional wear resistance and hardness. It exhibits excellent dimensional stability during heat treatment, making it ideal for precision tooling. While not as tough as shock-resistant grades, it offers good compressive strength and can handle high-stress applications. Its air-hardening property ensures minimal distortion, and its high chromium content provides moderate corrosion resistance, making it a reliable choice for long-lasting tooling in abrasive environments.
