D2 steel typically contains:

• Carbon: 1.50% - 1.60%
• Chromium: 11.00% - 13.00%
• Molybdenum: 0.70% - 1.20%
• Vanadium: 0.10% - 0.30%
• Manganese: 0.15% - 0.45%
• Silicon: 0.10% - 0.40%

This combination of elements results in a material that is both hard and tough, capable of withstanding significant wear and tear.

Properties

1. Hardness: D2 steel can achieve a hardness of up to 60-62 HRC after heat treatment, making it extremely durable.
2. Wear Resistance: The high chromium content provides excellent resistance to abrasion and wear.
3. Corrosion Resistance: While not as corrosion-resistant as stainless steel, D2 offers better resistance than many other tool steels due to its high chromium content.
4. Edge Retention: D2 steel maintains a sharp edge for a long time, making it ideal for cutting tools.

Applications

D2 steel is widely used in:

• Industrial Tools: Dies, punches, and shear blades benefit from D2's hardness and wear resistance.
• Knives: Popular among knife makers for its edge retention and durability, D2 is used in both kitchen and outdoor knives.
• Cutting Tools: Any application requiring a sharp, durable cutting edge can benefit from D2 steel.

Conclusion

D2 steel's combination of hardness, wear resistance, and durability makes it a favorite in the tool and knife manufacturing industries. Its ability to maintain a sharp edge and withstand significant wear ensures its continued popularity among professionals and hobbyists alike.
