154CM / CPM 154 Steel Guide: A Classic Workhorse

on

 154CM and its powdered metallurgy upgrade, CPM 154, are classic steels that have stood the test of time in the knife world. Known for their reliability and versatility, these stainless steels are workhorses in EDC, outdoor, and tactical blades. In this guide, we’ll explore their composition, properties, and why they remain popular choices for knife enthusiasts in 2025.

What is 154CM / CPM 154 Steel?

154CM, originally developed by Crucible Industries, is a stainless steel with 14% chromium, 1.05% carbon, and 4% molybdenum. CPM 154 takes it a step further with powder metallurgy, refining the grain structure for improved performance. Both offer a solid mix of corrosion resistance, edge retention, and toughness, making them staples in knives from brands like Benchmade.

Key Properties of 154CM / CPM 154

  • Edge Retention: Decent edge holding, better in CPM 154, though not as extreme as K390.
  • Corrosion Resistance: 14% chromium provides good rust resistance, though less than M390.
  • Toughness: Stronger than brittle steels, with CPM 154 edging out 154CM (typically 58-61 HRC).
  • Sharpenability: Easier to sharpen than M4, but not as simple as 14C28N.
