- Boron steel.
- Hardness: 48 +/2 HRC guaranteed via the use of an automatic control system in heat treatment. This hardness ensures flexibility and the ability to absorb impacts without breaking, providing the disc a longer life-span, even in the most severe soil conditions.
- Lathed, precise and uniform edges, obtaining optimal soil penetration.
- Surpasses the hardness test.
- Discs are used for harrow and ploughs.
