TNW is a 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. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on high temperature performance as well as forming, heat treating, and machining. Filing Code: TS-433. Producer or source: Latrobe Steel Company.
