What Is 440C Stainless Steel?
440C is a high-chromium martensitic stainless steel that belongs to the 440 series. This steel type contains approximately 17-18% chromium and 1% carbon, making it one of the most corrosion-resistant options in the knife blades materials category.
How Does 440C Compare to Other Knife Steels?
When comparing different steel types, 440C stands out for its balance of properties:
- Higher carbon content than 440A and 440B
- Better edge retention than many budget steels
- Excellent corrosion resistance
- Good balance of hardness and toughness
Why Do Some Knifemakers Love 440C?
Many custom knifemakers appreciate 440C for several reasons:
- Easy to heat treat
- Good machinability
- Takes a sharp edge
- Maintains reasonable costs
What Are the Main Advantages of 440C Steel?
The benefits of choosing a 440C steel knife include:
- Excellent corrosion resistance
- Good edge retention
- Relatively easy to sharpen
