CPM Cru-Wear

Premium Tool Steel (Non-Stainless)60–64 HRCCrucible Particle Metallurgy (CPM)

Composition

Core alloying elements define the baseline trade-off between wear resistance, corrosion behavior, and toughness.

Material Overview

CPM Cru-Wear is a powder metallurgy tool steel developed by Crucible Industries as a high-performance alternative to conventional tool steels like D2. It offers improved toughness, better wear resistance, and finer carbide distribution thanks to the CPM process. While it is not stainless, it provides a very balanced performance profile, making it popular among knife makers who want durability and strong cutting performance without extreme brittleness.
