They combine thermal stability (600-700?S) with the high hardness (HRC 63-70) and the increased resistance to plastic deformation. As a result the application of high-speed steels it became possible to increase the cutting speed 2-4 times (but newer steels s intermetallide by strengthening even 5-6 times) and to increase the durability of tools 10-40 or more times in comparison with obtained for the tools from non-heat-resistant steels. These advantages they are manifested with the cutting: with the increased speed, i.e., under the conditions of heating cutting edge, or with the lower speed, but with the high pressure. For understanding of the special features of properties and field of uses them it is important that reduction in their hardness on HRC 2-4 in comparison with the obtained maximum can be accompanied by worsening in the viscosity, strength and wear resistance. High-speed steel R6M5 it is necessary in the use in the state of high hardness and with the work without the large dynamic loads. High-speed steel of the moderate thermal stability they preserve hardness HRC 60 after heating (4ch) to 615-620?S. They are suitable for the cutting of steels and cast irons with the hardness to HB 250-280, i.e., the majorities of construction materials, and are used most widely (78-80% of the general production of high-speed steels). The characteristic representatives of this group are they became R18 and those more rational alloyed: tungsten (steel Of r12) and tungsten-molybdenum (steel R6M5). Steels of normal thermal stability include tungsten R18 and tungsten-molybdenum R6M5 of steel (table. 3). These steels have hardness in hardened state 63… 64 HRC, transverse strength of 2900… 3400Mpa, impact toughness 2,7… 4,8Dzh/m^2 and thermal stability 600… 620°S. The trademarks of steel indicated received the widest acceptance with the production of cutting tools. The volume of the production of steel R6M5 reaches 80% of entire volume of output of high-speed steel. It is used with working of structural steels, cast irons, nonferrous metals, plastics.
