Characteristics and types of high-speed steel

Technical characteristics

Brand R6M5, R12F3, Р8М3К6С, Р8М3, Р8М5, P9, P18 used for the production of high speed tool. Favorably great heat resistance, have a high estimated hardness. Alloying elements — vanadium, molybdenum, cobalt, tungsten. The tools are made from these grades of steel, very durable, with materials at high speeds is not softened at a high temperature (600°C) and do not lose resistance to wear.
