Material Notes:
DuraTech A11 powder metal tool steel a versatile air-hardening tool and die steel which provides extremely high wear resistance in combination with relatively high impact toughness. A very large volume of hard vanadium carbides provides the high wear resistance. The good impact toughness is the result of the fine grain size, small carbides, and superior cleanliness of the powder metallurgy (PM) microstructure. DuraTech A11 offers substantially better wear resistance than the high-carbon, high chromium die steels such as D2 and D7.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
