What is D2 Tool Steel?
D2 tool steel is a versatile and widely used grade in the cold-work category of tool steels, classified under the AISI (American Iron and Steel Institute) system. Its defining characteristic is a high concentration of carbon (approximately 1.5%) and chromium (approximately 12%). This specific chemical balance results in a microstructure rich in large, hard chromium carbides, which are the source of its outstanding wear resistance.
Unlike many other tool steels that require rapid quenching in oil or water, D2 is an air-hardening steel. This means it hardens effectively with a slower cooling rate in air, which significantly minimizes distortion and the risk of cracking during the heat treatment process. This feature ensures exceptional dimensional stability, making it ideal for creating complex or large tools where tight tolerances must be maintained. You can rely on D2 for its superior compressive strength and edge retention, which are crucial for long production runs in stamping, forming, and cutting operations.
Common designations for this grade include:
- AISI: D2
- UNS: T30402
- DIN: 1.2379
- BS: BD2
- JIS: SKD11
