High-speed tool steel
general characteristics
Fast-cutting steel is produced in accordance with the norms of GOST 19265−73. Used in the production of metal cutting tools, which is designed for high-speed cutting. Doped with tungsten, molybdenum, vanadium, cobalt, which provides high heat resistance, redness, hardness.
Marking
The number indicated after the letter «P» means the average content of tungsten (from the total mass in percent, the letter B is skipped). Then the letters M, K, and F indicate the percentage of molybdenum, cobalt, vanadium.
