Note. On demand of the consumer steel of this grade can be produced with the presence of fixed nitrogen (from 0.05% to 0.10%).In this case, the symbol looks like R6AM5. Produce about the technology of electroslag remelting, the steel is marked with the additional letter W.

Technical characteristics

Steel R6M5 belongs to the group of high carbon high speed tool steels of high hardness and wear resistance for the manufacture of cutting tools — drills, reamers, core drills, milling cutters, etc., as well as a tool for plastic deformation of steels (the recuperator, punches, matrices, etc.). Steel R6M5 is of high wear resistance and strength under shock loading, and therefore is also effective for the manufacture of tools for cold extruding and pressing.

Physical characteristics

  • Density, kg/m3 8300;
  • Coefficient of thermal conductivity, W/mgrad and 20.4;
  • Specific heat, j/kgrad — 510;
  • The coefficient of thermal expansion, µm/deg on 13.1;
  • Elastic modulus, GPA 210.

Mechanical properties (quenching+vacation t° 540±100°C)

  • The limit of temporary resistance, MPa — 3200…3600 MPa;
  • Rockwell hardness, HRC — 62…66;
  • Impact strength, kJ/m2 — 42;
  • Red Hardness, °C — 620.

Treatment

Steel is prone to decarburization. Temperature range of forging 850…1100°C. Hardness after annealing Brinell — 255НВ. Cooling after forging must be carried out in the wells, otherwise probably the formation of surface microcracks.
