Technical characteristics

Tool steel R18 is used to produce drills, cutters and cutters for machining metal, ebonite and ceramics. This grade belongs to the class of high-speed steels, as evidenced by the letter "P". As for the number, 18 is the average percentage of tungsten in the alloy. The full chemical composition is regulated by GOST 19265-73 standards.

The percentage composition of GOST 19265-73.

C Si Mn Cr Mo W V Ni Cu Co S P Fe
0.75 - 0.83 0.2 - 0.5 0.2 - 0.5 3.8 - 4.4 ≤1 17 - 18.5 1 - 1.4 ≤0.6 ≤0.25 ≤0.5 ≤0.03 ≤0.03 base

Alloying has a multidimensional effect on the merits of steel. 4% Cr increases hardness and corrosion resistance. Nickel gives the alloy ductility; 17-18% W - hardness, red resistance. Vanadium increases strength, impact and abrasion resistance; cobalt increases heat resistance, magnetic permeability. Molybdenum makes the alloy red resistance, strength, resistance to oxidation at high temperature. Manganese content above 1% increases hardness, impact strength, wear resistance. Titanium increases stability, corrosion resistance; aluminum, scale resistance; niobium, acid resistance. Copper increases ductility, prevents rusting. It is worth noting that the mechanical, physical and technological properties are at a fairly high level and largely depend on the processing. A circle made of this steel grade at a tempering temperature of 600 °C has:

  • good toughness;
  • wear resistance;
  • weldability without limitations;
  • Tensile strength over 2100 MPa.
