Conclusions

  1. 1.

    Sichromal 12 after deformation has low plastic properties and low impact toughness (less than 1 kg-m/cm2) at room temperature.

     
  2. 2.

    At elevated temperatures the plasticity increases sharply: at 100°C δ=20% and ψ=50%. The steel has a discrete ductile-to-brittle temperature of 150–200°C.

     
  3. 3.

    Increasing the plasticity of Sichromal 12 requires annealing or quenching. However, quenching is probably impossible to use for massive pieces because of the danger of cracking.
