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.

AISI Type M30 is a high-speed tool steel containing 8% molybdenum and 5% cobalt. It provides long life in machining difficult-to-cut metals, such as heat-resisting alloys and superalloys, and is recommended for cutting tools requiring a good combination of suitable toughness with optimum cutting qualities.
