CPM Tool Steel Sheet

CPM® Tool Steel Sheet

Just as CPM® processing can allow higher alloy content for red hardness and wear resistance in high speed steels, it can also be used to produce high alloy cold work tool steels for increased wear resistance. The wear resistance of a tool steel is determined by the heat treated hardness and the amount and type of hard alloy carbides present in the microstructure. The cold work tool steels known for superior wear resistance typically contain significant amounts of vanadium with sufficient carbon to form high volumes of vanadium carbides.

CPM 1V® has shock resistance close to S-7 and wear resistance close to A-2. CPM 3V® provides impact toughness approaching that of S-7 and wear resistance higher than D-2. CPM 9V® is a modification of CPM 10V® with lower carbon and vanadium to improve toughness and heat check resistance. These enhanced properties permit CPM 9V® to perform well in problem applications where high carbon, high chromium tool steels, such as CPM 10V® or the high speed steels, lack sufficient toughness or where lower alloy tool steels and hot work tool steels lack sufficient wear resistance. CPM 10V® has four times the wear resistance of D-2 at the same toughness. CPM 15V® was developed to withstand extreme wear conditions where carbide fractures and CPM 10V® is not wear resistant enough.

Crucible continues to develop specific high vanadium CPM® grades to meet a variety of wear/toughness requirements. Bridge alloys such as CPM 110V® and CPM S125V® are two newer alloys that can be produced in sheet and plate.
