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.BRAETUF is a modified version of AISI Type M44 high-speed steel having superior cutting performance and superior wear resistance. It is an ultrahard high-speed steel recommended for machining highly alloyed steels at high hardnesses and also heat teated high temperature alloys.
