| DuraTech NINE is an air-hardening, powder metal tool steel that provides very high wear resistance in combination with high impact toughness. A large volume of hard vanadium carbides provides the high wear resistance. DuraTech NINE contains less carbon and vanadium than DuraTech A11, which results in a lower attainable hardness, slightly lower wear resistance, but a significant increase in toughness. The lower carbon content also enables DuraTech NINE to be used in warm and hot work applications where resistance to thermal fatigue cracking is important. DuraTech NINE may be used in unique tooling applications for improved toughness compared to DuraTech A11 and high speed steels, and improved wear resistance compared to D2 and other tool steels. DuraTech NINE is widely used for plastic injection feed screws, non-return valves, shear blades, and forging dies. Information Provided by Timken Latrobe Steel. Timken sold Latrobe in December 2006.
