Standard carbon steel blades wear out rapidly in abrasive Indian soils containing quartz and stone gravel, losing their cutting radius within 50 to 80 acres. Balwan Agro utilizes high-carbon Boron steel blades that undergo automated induction hardening to 50±2 HRC. This optimal hardness provides both exceptional surface wear resistance and high core ductility, preventing sudden shattering when hitting embedded boulders.
