High Speed Steels
High-speed steels contain molybdenum and tungsten. They are hardened to 62-67 HRC and maintain this hardness in service temperatures as high as 540° C. 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.

The properties of this category steel are:
