Tool Steel Induction Hardening Services in Ludhiana
Used in dies, punches, molds, and cutting tools, materials like D2, H13, and M2 require exceptional hardness and wear resistance to handle extreme mechanical stress.
Why Induction Hardening for D2, H13, and M2 Steels?
Each tool steel grade has unique mechanical and chemical properties that make it suitable for specific applications. Here’s how induction hardening enhances their performance:
| Tool Steel | Properties | Effect of Induction Hardening |
|---|---|---|
| D2 (High Carbon, High Chromium) | Excellent wear resistance | Improves surface hardness to 58–62 HRC; perfect for dies and punches. |
| H13 (Chromium-Molybdenum Hot Work Steel) | High thermal resistance | Enhances hot strength and fatigue life for forging dies and extrusion tools. |
| M2 (High-Speed Steel) | Red hardness and toughness | Increases wear resistance while preserving high-temperature performance. |
The Tool Steel Hardening Process
- Pre-Inspection: Components are cleaned and checked for surface contaminants, geometry, and pre-machining tolerances.
- Induction Heating: The part’s surface is heated using a medium or high-frequency coil tuned to the material’s properties and section thickness.
- Controlled Quenching: Instant cooling through polymer or water quenching ensures rapid transformation to martensite without cracking.
- Tempering: Post-hardening tempering relieves internal stresses and refines hardness uniformity.
- Testing & Verification: Hardness and case depth are validated using Rockwell HRC and microstructural testing.
Heat Treatment Parameters for D2, H13, and M2 Steels
| Steel Type | Austenitizing Temperature (°C) | Quenching Medium | Target Hardness (HRC) |
|---|---|---|---|
| D2 | 1000–1050 | Polymer / Air | 58–62 |
| H13 | 1020–1050 | Polymer / Air | 50–54 |
| M2 | 1180–1220 | Polymer / Oil | 60–65 |
Benefits of Tool Steel Induction Hardening
- Improved Surface Hardness: Increases resistance to wear and impact.
- Localized Heating: Only functional zones are hardened, minimizing distortion.
- Enhanced Tool Life: Reduces wear and micro-cracking in dies and punches.
- Energy Efficiency: Lower power consumption compared to furnace hardening.
- Consistent Results: Automated parameters for uniform hardness and depth.
