Engineering & Design Overview
Hero Blades Plain Concave Discs are crafted from prime European and Indian boron alloy steel. Designed for heavy disc harrows, disc ploughs, and offset stubble cultivation, our blades deliver effortless soil penetration and complete residue burial without edge fracturing.
Every disc undergoes continuous automated induction quenching to achieve a through-hardened 48 to 52 HRC rating with a ductile, shatterproof core.
Precision hot-dished spherical geometry ensures maximum soil turnover with minimum tractor drawbar requirement. Fully compatible with major international disc harrow gang configurations.
Key Engineering Features
- Certified Boron Steel 30MnB5 alloy composition
