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.TNW is a DESEGATIZED* high-speed steel. It has an optimum alloy composition that combines the good toughness characteristics of a high-molybdenum steel and the excellent abrasion resistance provided by a 2% vanadium content. TNW is a popular choice for twist drills, taps, reamers, router bits, end mills and other similar cutting tools. Also its good toughness makes it well suited to punches and other difficult cold-forming tools requiring the properties of a high-speed steel.
