What Is CPM 154 Steel?
CPM 154 has the same chemistry as 154CM, but powder metallurgy makes the carbides smaller and more uniform. That helps toughness and lets it take a polished edge.
CPM 154 Steel Properties
- Edge retention: Good.
- Toughness: Good.
- Rust resistance: Very good.
- Ease of sharpening: Moderate.
