Hardox is the world's leading abrasion-resistant steel, manufactured by Swedish steelmaker SSAB. Available in grades from 400 to 600 HBW (Brinell hardness), Hardox combines extreme hardness with excellent toughness and weldability.
In excavator attachments, Hardox is used for wear plates, cutting edges, and high-impact areas. The most common grades are:
- **Hardox 400**: General-purpose wear resistance (400 HBW)
- **Hardox 450**: Enhanced wear resistance for demanding applications (450 HBW)
- **Hardox 500**: Extreme wear resistance for quarry and mining (500 HBW)
- **Hardox HiTuf**: Maximum impact resistance with good wear properties
