View Sample Alloy Digest Data Sheet (PDF)

Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.

LESCALLOY BG42 VIM-VAR combines the tempering, hardness and hardness-retention characteristics of AISI M50 high-speed steel with the corrosion and oxidation resistance of AISI Type 440C stainless steel. LESCALLOY BG42 VIM-VAR is double vacuum melted (VIM = Vacuum Induction Melted and VAR - Vacuum Arc Remelted) to consistently assure good cleanliness and superior properties. It is used for bearings, gears, ball screws and other aerospace applications.
