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.FAGERSTA M-7 is a molybdenum-type high-speed steel similar to AISI Type M1, but with higher percentages of carbon and vanadium than M1. The higher levels of carbon and vanadium provide an improved cutting efficiency without significantly lowering toughness. The many applications of FAGERSTA M-7 include boring tools, end mills, lathe tools, twist drills, thread-rolling dies and wood-working tools.
