How does the hardness of a knife blade affect its performance?
The impact of a knife blade's hardness on its performance primarily lies in the balance between wear resistance, toughness, and suitability for specific applications. A detailed analysis is provided below:
I. The Relationship Between Hardness and Wear Resistance
High Hardness (HRC 50–60)
Significantly improved wear resistance, with an indentation depth of approximately 0.08 mm, suitable for precise cutting (e.g., sashimi knives, utility knives).
However, excessively high hardness (e.g., HRC 60 or above) may increase brittleness, leading to chipping or breakage.
Medium-low hardness (HRC57 or below)
Poor wear resistance, but easier to sharpen, suitable for outdoor tools requiring frequent re-sharpening (e.g., chopping knives).
II. The Conflict Between Hardness and Toughness
Toughness requirements: High-impact scenarios (e.g., chopping) require a hardness of around HRC57 for stronger fracture resistance.
Balance between hardness and toughness: General-purpose knives are recommended to be in the HRC 50–60 range, balancing sharpness and impact resistance.
III. Practical Application Recommendations
Precision cutting: Choose high-hardness blade plates (such as 7-chromium molybdenum vanadium steel) with HRC 58–62.
High-intensity work: Prioritize materials below HRC 57 to avoid brittle fractures.
