Conclusions

  1. 1.

    The heat resistance and mechanical properties of steels for hot working dies with about 0.4% C (4Kh4V2M2FS type) are increased by alloying with carbide-forming elements (chromium, tungsten, molybdenum, vanadium) only up to a certain limit, above which the effect is small or negative.

     
  2. 2.

    For steels for hot working dies with about 0.4% C the optimal concentrations are ∼2.5% Cr, ∼1.0% W, ∼1.5% Mo, and ∼1.0% V, which provide a good combination of heat resistance, strength, and plasticity after tempering 2 h at 620–630°C: HRC 47-50; σb = 175–185 kg/mm2; σ0.2 = 155–165 kg/mm2; ψ=40–42%;an = 4–5 kgm/cm2 at 20°C.
