Material Notes:
CBS-223 VIM-VAR steel is a double vacuum melted carburizing steel with high hot hardness characteristics. Double vacuum melting sequentially combines vacuum induction melting with VACARCâ„¢ remelting to provide for superior cleanliness, which imparts improved fatigue strength and fracture toughness to the alloy. Its high hot hardness and the improved properties readily identify CBS-223 VIMVAR steel for use as gears, shafts and bearings in helicopter and other aerospace applications.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
