Description
Take a look at the Facts of the New *CPM S35VN* Blade Steel:
1. The Name: CPM S35VN
CPM: Stands for Crucible Particle Metallurgy. This is a manufacturing process developed by Crucible Industries where steel components are powdered, melted, atomized, and subjected to high pressure/temperature.
This process results in an incredibly fine, uniform grain structure, which significantly improves the steel’s toughness and makes it easier to grind and polish compared to conventionally melted steel.
S: Indicates it is a stainless steel.
35VN: The specific alloy designation. The “V” denotes the use of Vanadium, and the “N” denotes Niobium ($Nb$).
2. Composition & Properties
CPM S35VN was developed as a Vastly improved version of the very popular *CPM S30V* steel.
The addition of Niobium ($Nb$) refines the grain structure even further, resulting in better performance:
| Property | Rating | Benefit for Knives |
| Edge Retention | Excellent | Holds a razor-sharp edge for a long time. |
| Toughness | Great | Highly resistant to chipping or breaking, making it suitable for larger or hard-use blades. |
| Corrosion Resistance | Excellent | High chromium content (around 14%) makes it highly resistant to rust and staining. |
| Sharpening | Superb | It is notably easier to sharpen and finish than the older S30V, a feature appreciated by knifemakers and users alike. |
