Steel & quality
The steel behind the edge.
30MnCrB5 boron steel — steel made for hard soil and strong tractors. Compare grade and hardness, not just brand paint.
Material
30MnCrB5, on the record.
Every blade starts as certified 30MnCrB5 boron steel sheet. Here is exactly what is in it — and what the heat treatment delivers.
| Element | Content | Role |
|---|---|---|
| Carbon (C) | ~0.30% | Core strength |
| Manganese (Mn) | 1.10–1.40% | Toughness and hardenability |
| Chromium (Cr) | 0.30–0.60% | Wear resistance |
| Boron (B) | Trace | Deep, even hardness |
| Silicon (Si) | Balanced | Strength |
Why it matters in the field
What good steel does.
High strength
Resists fatigue through long hours of heavy tillage.
Sharp edge
Holds its cutting edge instead of rounding off mid-season.
Less bending
Tough core means less bending and cracking on stones and hard pan.
Even hardness
Consistent 48–52 HRC across every blade in the batch.
Our promise
