Description
AISI D2 Tool Steel
AISI D2 tool steel is a high-carbon, high-chromium tool steel known for its excellent wear resistance, toughness, and ability to maintain hardness at elevated temperatures. As a cold-work tool steel, D2 is commonly used for making tools that require high wear resistance and strength. Its unique composition allows it to perform exceptionally well in applications that demand durability and longevity.
Key Features of AISI D2 Tool Steel:
- Exceptional Wear Resistance: D2 steel has high wear resistance due to its high carbon and chromium content, making it ideal for tools that undergo abrasive wear.
- High Hardness: After heat treatment, D2 achieves hardness levels typically in the range of 55-62 HRC, allowing tools to maintain their cutting edges for extended periods.
- Good Toughness: Despite its high hardness, D2 maintains good toughness, making it resistant to chipping and cracking under impact.
- Excellent Dimensional Stability: D2 exhibits minimal distortion during heat treatment, ensuring that tools retain their intended dimensions.
Applications of AISI D2 Tool Steel:
- Die Making: D2 is widely used in the manufacturing of dies for stamping, molding, and other applications due to its wear resistance and hardness.
- Blades and Cutters: It is commonly used for making cutting tools such as blades and cutters that require sharp edges and durability.
- Punches: AISI D2 is an excellent choice for punches, offering the necessary strength and resistance to wear.
- Forming Tools: D2 is suitable for various forming tools that need to withstand high impact and wear.
- Industrial Knives: The steel is frequently used in industrial knives, where durability and cutting performance are paramount.

Grades of AISI D2 Tool Steel:
| Grade | Key Features | Applications |
|---|---|---|
| D2 | High wear resistance, excellent hardness, good toughness, minimal distortion during heat treatment | Die making, blades, cutters, punches, forming tools, industrial knives |
| D2 PM (Powder Metallurgy) | Enhanced wear resistance and toughness due to refined microstructure | Precision tooling, high-performance industrial applications |
Heat Treatment Process:
The heat treatment process for AISI D2 typically involves austenitizing at temperatures ranging from 1020°C to 1080°C (1868°F to 1976°F), followed by quenching in oil. The steel is then tempered at temperatures of 150°C to 200°C (302°F to 392°F) to achieve the desired hardness while reducing residual stresses.
Advantages of AISI D2 Tool Steel:
- Outstanding Wear Resistance: D2’s high carbon and chromium content provide excellent wear resistance, making it ideal for heavy-duty applications.
- High Hardness: The steel retains hardness even under high-temperature conditions, allowing for long-lasting cutting edges.
- Good Toughness: Despite its hardness, D2 has good toughness, reducing the likelihood of tool failure under stress.
- Dimensional Stability: AISI D2 exhibits minimal distortion during heat treatment, ensuring tools maintain precise dimensions.
Conclusion:
AISI D2 tool steel is a premier choice for applications requiring superior wear resistance, high hardness, and excellent toughness. Its unique properties make it highly effective for manufacturing cutting tools, dies, punches, and other industrial tools that operate under severe conditions. With its ability to withstand high impact and maintain sharpness, D2 tool steel remains a popular option among manufacturers and toolmakers seeking durability and performance in their tooling solutions.
