HIGH SPEED STEEL
High-speed steels (rapids, quick-cuts) belong to special-purpose tool steels. All tool steels are characterized by high hardness in the cold and hot state and high resistance to plastic deformation. For high-speed steels, the set of characteristics is supplemented by red resistance — preserving the properties when the tool is heated to a temperature close to 600 º C, which is important for processing hard metals by cutting at high speed. Alloying carbide-forming additives: cobalt, tungsten, vanadium and molybdenum give red resistance and hot strength to steel.
We produce high-speed steel of the following grades:
- M35 (Russian grade R6M5K5)
- M1 (Russian grade R6M5)
- T1 (Russia grade R18)
Tool steel should have high hardness, wear resistance, sufficient strength and toughness (for impact tools).
The cutting edges can be heated to a temperature of 500 … 900 ° C, therefore, heat resistance is an important property, i.e., the ability to maintain high hardness and cutting ability during prolonged heating (red resistance).
HIGH ALLOY STEEL
High-alloy steel, in addition to the main components — iron and carbon, also contains a number of additional additives, their total amount exceeds 10%. Alloying additives, which are introduced into the composition of such steels, are intended to significantly improve the physical as well as mechanical properties of the base alloy.
