CP4M Material Tool Steel
CP4M Material
Cr-Mo-V alloyed, secondary hardenable cold work tool steel with high toughness, dimensionally stable, better weldability and through-hardenability (compared to the carbide rich cold work tool steel 1.2379). Excellent base material for nitriding or coating (CVD, PVD).
Manufactured by Dörrenberg Edelstahl.
Area of Application
Deep drawing, punching and cutting tools, tools for hot and cold forming of higher tensile sheet material.
