Material Notes:
DuraTech Xtreme tool steel is a medium-carbon, powder metallurgy tool steel 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 powder 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 60s Rockwell C, the unique properties of DuraTech Xtreme make it an excellent choice for tooling applications which require both high strength and high impact toughness, heat resistance, or all of the above. DuraTech Xtreme should be considered for the most extreme 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 toughnessTimken sold Latrobe in December 2006.
