HSS steels

HSS steels contain molybdenum and tungsten. Characteristics of this steels are high hardness in hot and cold, high toughness and high wear resistance.  They can be hardened to 62-67 HRC. Typical applications: cutting-off tools (knives, drills, milling cutters, etc.), rolls for cold rolling, cold-work tools.
