The main performance parameters of high speed steel directly depend on the quantitative and qualitative composition. The presence in material of Nickel and chromium offers good corrosion resistance. These elements form on the surface of the tape strong protective film oxide type, and the additional alloying with such elements as tungsten, molybdenum, vanadium ensures the stability of working characteristics of raw materials and increases the resistance. These steels are resistant to high temperatures (the so-called red hardness): They do not lose their hardness even when the temperature reaches red heat. High iron content significantly reduces the alloy.


High speed steel are manufactured from heat-resistant alloyed corrosion-resistant grades steel, which melted in open arc furnaces. The basis of the raw materials are iron and chrome. The percentage of alloying elements such as tungsten, molybdenum, vanadium reflected in the marking. Quantitative content in the material such chemical elements as manganese and silicon, usually in the range of 1%. Such material may for a long time to work if at t° 1000 °C with no loss of technological qualities. In marking the number after the letter «P» indicates the average tungsten content Then, after the letters M, f and K indicate the percentage of molybdenum, vanadium and cobalt
