Description
D5 Tool Steel
D5 tool steel is a high-carbon, high-chromium air-hardening tool steel in the D-series, designed for extreme wear resistance and superior hardness. It belongs to the cold-work tool steel category, which is commonly used for applications involving high-pressure, abrasion, and impact resistance. D5 tool steel has a higher chromium content compared to other D-series steels, providing better corrosion resistance and wear resistance. It is ideal for making tools and parts subjected to extreme wear and abrasive conditions, maintaining hardness and dimensional stability even under high-stress operations.
Key Features of D5 Tool Steel:
- High Wear Resistance: D5 tool steel is known for its exceptional resistance to wear, making it ideal for tools exposed to abrasive conditions.
- Corrosion Resistance: The high chromium content provides some corrosion resistance, adding to the longevity of tools in harsh environments.
- Air Hardening: D5 hardens in air, reducing the risk of cracking or distortion during the hardening process.
- High Hardness: It maintains high hardness after heat treatment, essential for tools requiring long-term durability.
Applications of D5 Tool Steel:
- Cold Work Dies and Punches: D5 is widely used in the production of dies and punches for cold working applications, where extreme wear resistance and hardness are required.
- Shear Blades and Trimmers: Due to its exceptional wear resistance, D5 is used in the manufacturing of shear blades, trimmers, and other cutting tools for industrial processes.
- Metal Stamping and Forming Tools: D5 tool steel is suitable for stamping and forming tools that require resistance to impact, wear, and chipping.
- Industrial Knives: D5 is used in the production of industrial knives for cutting hard materials, where prolonged sharpness and toughness are critical.
- Rolls for Cold Rolling: In industries that require cold rolling, D5 is often used for rolls that must endure heavy wear and maintain their form over long periods.
Chemical Composition of D5 Tool Steel:
| Element | Percentage (%) |
|---|---|
| Carbon (C) | 1.45 – 1.60 |
| Manganese (Mn) | 0.20 – 0.60 |
| Silicon (Si) | 0.20 – 0.50 |
| Chromium (Cr) | 11.00 – 13.00 |
| Vanadium (V) | 0.10 – 0.25 |
| Molybdenum (Mo) | 0.50 – 1.00 |
Grades of D5 Tool Steel:
| Grade | Key Features | Applications |
|---|---|---|
| D5 | High wear resistance, corrosion resistance, air hardening | Cold work dies, punches, shear blades, knives, cold rolling |
| D5 Modified | Enhanced toughness and wear resistance | Used in applications with extreme wear conditions |
Heat Treatment Process:
D5 tool steel is heat treated by heating to austenitizing temperatures (usually around 1750°F to 1850°F), followed by air cooling. This air-hardening process helps maintain dimensional stability and hardness. After air cooling, tempering is performed to achieve the desired toughness and hardness based on the application requirements.
Advantages of D5 Tool Steel:
- High Wear Resistance: D5’s high chromium and carbon content provide excellent wear resistance, making it ideal for prolonged use in harsh conditions.
- Dimensional Stability: The air-hardening nature of D5 minimizes distortion during heat treatment, making it suitable for precision tools.
- Long Tool Life: Its high hardness and resistance to wear extend the life of tools, reducing the need for frequent replacement.
- Corrosion Resistance: The high chromium content adds a degree of corrosion resistance, especially useful in environments where tools are exposed to moisture or chemicals.
