Through-hardened 30MnB5 aggressive notched disc blade for European high-speed compact disc cultivators
Hot-formed and die-quenched for high-speed residue incorporation at 14–20 km/h. Deep-scalloped notches slice tough Bt corn stalks and cover crops cleanly while uniform HRC 48–52 boron steel martensite resists edge rolling and catastrophic shattering in stony fields.
