FAQ
1. Why choose forged chains over welded/rolled alternatives?
3× Longer Service Life: Directional grain flow resists crack propagation
Higher Safety Factors: No weld seams (common failure points in drag chains)
Proven in Mining: Withstand 50% more impact energy than DIN 764 standard
2. What makes the X458 series suitable for extreme conditions?
| Feature | Mining Benefit | Trolley Benefit |
|---|---|---|
| Material | 42CrMo4 alloy (850-1200MPa TS) | 20MnCr5 (optimized for fatigue) |
| Surface Treatment | QPQ nitriding (30μm) | Zinc-nickel plating (15μm) |
| Temperature Range | -40°C to +250°C | -30°C to +150°C |
3. Can you match our existing chain specifications?
Yes, we replicate:
