EN47 STEEL
EN47 for spring characteristics and shock resistance.
EN47 is a high-carbon alloy spring steel supplied in the rolled condition. It is suitable for oil hardening and tempering processes. In the hardened and tempered state, EN47 combines excellent spring characteristics with good wear and abrasion resistance.
When hardened, EN47 offers high toughness and superior shock resistance, making it ideal for applications subject to dynamic stresses, impacts, and vibrations.
- High resilience and fatigue strength
- Excellent toughness and shock resistance
- Good wear and abrasion resistance
- Suitable for oil hardening and tempering

| Hardening | 650 – 700 °C / 820 – 850 °C | Preheat slowly to 650 – 700 °C; Heat to 820 – 850 °C; Hold until uniform temperature is reached; Quenching: Oil |
| Tempering | 400 – 600 °C | Depending on required hardness/toughness balance; Hold for at least 1 hour per 25 mm thickness; Cooling: Air cool; Final Hardness: 48 – 52 HRC |
Built for demanding applications.
EN47 for strength under stress and vibration.
EN47 is a medium-carbon, chromium alloy spring steel with excellent toughness, shock resistance, and fatigue strength. It is best suited for springs in heavy-duty automotive and industrial applications, especially where high stress and vibration resistance are required.
