General characteristic

High-speed steels are produced in accordance with GOST 19 265-73. They are used for production of metal-cutting tools designed for high-speed cutting. The alloying of high-speed steel with tungsten, molybdenum, vanadium and cobalt provides hardness, heat resistance and redness resistance of steel.

Marking

The number after "P" indicates the average tungsten content (as a percentage of the total mass, the letter B is omitted). Then after the letters M, F and K indicate the percentage of molybdenum, vanadium and cobalt.
