Speed steel produced according to GOST 19 265−73. They are used for the production of cutting tools, designed for vysoskorostnoy cutting mode. Doping of high-speed steel tungsten, molybdenum, vanadium and cobalt provides hardness, heat resistance and red hardness of steel.
The number after the letter «P» indicates the average tungsten content (percentage of total weight, the letter B is skipped). Then, after the letters F, K and F show the percentage of molybdenum, vanadium and cobalt.
