CPM 1V Powder Metal Tool Steel Round Bar

CPM 1V tool steel is a medium-carbon, powder metallurgy tool steel that exhibits very high impact toughness. The unique chemical composition results in tooling which has an outstanding combination of properties including very high impact toughness, very good hot hardness, and good wear resistance. The impact toughness is enhanced by the fine grain size, small carbides, and superior cleanliness of the pwder metallurgy (PM) microstructure.

Typically, when selecting a tool steel, one must choose between high strength or high toughness, with a compromise in the other of these two properties. However, with an attainable hardness in the low 60's Rockwell C, the unique properties of CPM 1V make it an excellent choice for tooling applications that require both high strength and high impact toughness, heat resistance, or all of the above.

 

CMP 1V should be considered for service in blanking dies, sizing dies, shear blades, cold and hot forging punches, forging dies, gear rolling dies, and many other applications where a combination of strength and toughness is required. CPM 1V should also be considered for severe applications where only steels such as S7, A9, and the high-alloy hot work steels have been suitable.

Impact Toughness
Its CPM microstructure gives 1V high impact toughness superior to that of the shock-resistant tool steels such as S7.

Wear Resistance
Its vanadium content imparts 1V with wear resistance slightly better than A2.

Temper Resistance
Because of its high alloy composition, CPM 1V has temper resistance similar to high speed steel (M2) and much better than most typical hot work tool steels as shown in the comparative temper curves below.
