What is 1.4112 Blade Steel?
1.4112 is a high-carbon stainless steel that’s part of the X90CrMoV18 family in the European EN standard. It’s closely related to AISI 440B, offering a balance of hardness, edge retention, and corrosion resistance. This makes it a preferred choice for premium kitchen knives, hunting knives, and surgical instruments.
With its chromium-rich composition and added molybdenum and vanadium, 1.4112 can withstand aggressive environments while maintaining a sharp, reliable edge for long periods.
Chemical Composition of 1.4112
| Element | Content (%) | Purpose |
|---|---|---|
| Carbon (C) | 0.85 – 0.95 | Increases hardness and edge retention |
| Chromium (Cr) | 16.00 – 18.00 | Provides corrosion resistance |
| Molybdenum (Mo) | 0.40 – 0.80 | Improves pitting resistance and strength |
| Vanadium (V) | 0.10 – 0.20 | Enhances wear resistance and grain refinement |
| Manganese (Mn) | ≤ 1.00 | Improves hardness and toughness |
| Silicon (Si) | ≤ 1.00 | Boosts strength and heat resistance |
| Phosphorus (P) | ≤ 0.040 | Controls steel processing |
| Sulfur (S) | ≤ 0.030 | Improves machinability |
Key Properties of 1.4112 Blade Steel
-
High Hardness Potential – Can be hardened to 56–60 HRC, ideal for high-end blades.
-
Excellent Corrosion Resistance – Suitable for both indoor and outdoor use, even in humid or coastal climates.
-
Good Wear Resistance – Maintains sharpness and cutting performance over extended use.
-
Edge Retention – Requires fewer sharpening sessions compared to lower-grade steels.
-
Polishability – Can achieve a mirror-like finish, enhancing both aesthetics and function.
Performance Comparison: 1.4112 vs. Other Blade Steels
| Steel Grade | Hardness (HRC) | Corrosion Resistance | Edge Retention | Ease of Sharpening |
|---|---|---|---|---|
| 1.4112 | 56–60 | Excellent | High | Moderate |
| 440C | 58–60 | Very Good | High | Moderate |
| AUS-8 | 57–59 | Good | Medium | Easy |
| VG10 | 59–61 | Excellent | Very High | Moderate |
1.4112 offers a balanced performance—slightly easier to sharpen than VG10 and with better corrosion resistance than AUS-8.
