High Speed Steel Round Bars
High-speed steels contain molybdenum and tungsten. They are hardened to 62-67 HRC, are used for machine tools such as drills, taps, hobs and broaching tools and in some cold forming applications. The properties required here are wear resistance, hot hardness and toughness which prevent breakage of cutting edges. This guarantees high tool life and low maintenance, and ensures a reproducible production process. Their properties are high wear resistance, high hardness at elevated and low temperatures, and excellent toughness. Typical applications: cutting-off tools (knives, drills, milling cutters, etc.), rolls for cold rolling, cold-work tools.
