	Crucible® CPM®-4V® is a powder metallurgy tool steel that offers high impact toughness and very good wear resistance. Developed for demanding industrial applications where a combination of strength, wear resistance and toughness is required, CPM-4V has significantly more carbon, vanadium, and molybdenum than CPM 3V. The result is a steel that is capable of a higher attainable hardness and even greater abrasion resistance than CPM-3V and significantly better toughness and wear resistance than D2. Despite these advanced performance qualities, CPM-4V has only 5% chromium--below the threshold of stainless steel--and therefore must be properly maintained to protect it from corrosion.

	Like conventional steels, particle metallurgy steels begin with a homogenous bath of molten high-alloy steel. However, instead of being poured into ingot molds, the molten steel is forced through a nozzle under high pressure to create a spray of small spherical droplets that quickly solidify into powder particles. The small size of the particles forms micro-ingots, drastically reducing the alloy segregation in the steel and ensuring an extremely fine, uniform carbide structure. This enhances the steel’s edge retention, as well as its grinding and polishing characteristics.
