Crucible Steel CPM® 3V® Tool Steel
Categories:	Metal; Ferrous Metal; Tool Steel
Material Notes:	CPM 3V is a new tool steel made by the Crucible Particle Metallurgy process, designed to provide maximum resistance to breakage and chipping in a highly wear-resistant steel. CPM 3V offers impact toughness greater than A2, D2, Cru-Wear or CPM M4, approaching the levels of S7 and other shock resistant grades, while providing excellent wear resistance, high hardness and thermal stability for coatings. Intended to be used at HRC 58-60 CPM 3V can replace high alloy tool steels in wear applications where chronic tool breakage and chipping problems are encountered. The CPM process produces very homogeneous, high quality steel characterized by superior dimensional stability, grindability, and toughness compared to steels produced by conventional processes.
