Technical characteristics

From tool steel R18 produces drills, cutters and milling cutters for metal, hard rubber, ceramics. This brand belongs to a class of high-speed steels, as evidenced by the letter «R». As for the numbers, 18 is the average of the percentage of tungsten in the alloy. Full chemical composition is regulated by standards GOST 19265−73.

Alloying has a multifaceted effect on dignity. 4% Cr increases the hardness, and korrozionnostojkoj. The Nickel gives the alloy ductility; 17−18% W — hardness, red hardness. Vanadium increases the strength, resistance to impact and abrasion; cobalt increases heat resistance, magnetic permeability. Molybdenum alloy imparts red-hardness, strength, opposition to oxidation at high temperature. The proportion of manganese is above 1% increases the hardness, toughness, durability. Titanium increases the stability, corrosion resistance; aluminium — resistance to scale formation; niobium — acid. Copper increases the ductility, prevents rusting. It should be noted that the mechanical, physical and technological properties are quite high and depend largely on processing. The range of this grade of steel at tempering temperature 600 °C has:

  • good viscosity;
  • durability;
  • weldability without restriction;
  • limit short-term strength of over 2100 MPa.
