What is DIN 1.2379 / AISI D2 / SKD11 Steel?
DIN 1.2379, also known as AISI D2 or SKD11, is a high-carbon, high-chromium cold-work tool steel known for its exceptional hardness, wear resistance, and durability. It belongs to the D series tool steels and is widely used for manufacturing cutting tools, industrial dies, and mold components.
This steel is air-hardened and offers excellent toughness while maintaining high hardness. It is often heat-treated to enhance its mechanical properties for heavy-duty industrial applications.
DIN 1.2379 / AISI D2 / SKD11 Steel – Chemical Composition
| Element | Percentage (%) |
|---|---|
| Carbon (C) | 1.40 - 1.60 |
| Chromium (Cr) | 11.00 - 13.00 |
| Molybdenum (Mo) | 0.70 - 1.20 |
| Vanadium (V) | 0.50 - 1.10 |
| Manganese (Mn) | 0.20 - 0.60 |
| Silicon (Si) | 0.10 - 0.60 |
| Phosphorus (P) | ≤ 0.030 |
| Sulfur (S) | ≤ 0.030 |
The high chromium content ensures excellent wear resistance and corrosion resistance, while molybdenum and vanadium enhance toughness and hardness.
