AL Tech DBL-3 is a molybdenum-type of high-speed steel containing relatively high carbon and vanadium to provide high resistance to abrasion. It shows marked superiority over many other high-speed steels in applications where abrasion resistance is a factor. Its many applications include taps, milling cutters, broaches and drills. This datasheet provides information on composition, physical properties, and hardness as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-347. Producer or source: AL Tech Specialty Steel Corporation.
