CP4M is a cold work steel, but a matrix type “next-generation” steel, specially developed by Dörrenberg. It is a Cr-Mo-V alloyed, secondary hardenable cold work tool steel with high toughness to prevent cracking and chipping. Dimensionally stable, easily machined, it has better weldability & through hardenability compared to the carbide rich cold work tool steel 1.2379. Excellent base for nitriding or coating.
CP4M is good for deep drawing, punching and cutting tools, tools for hot & cold forming of higher tensile sheet material. Good for die & mould making.
Whilst CPM4 is a superb next generation tool steel, the metallurgy of tool steels is complex, so if you need any help determining the best steel for a given application, please get in touch with details of your intended usage.
CP4M tool steel from AKM Steels is supplied soft annealed to max. 250 HB; quenched & tempered 280-235 HB. Available in wide plates & flats.
