Conclusions

  1. 1.

    In terms of increasing stability of austenite the steels investigated can be arranged in the following order: 08G2S; 08G2S+0.03% V; 08G2S+0.05% Nb; 08G2S+0.02% Nb+0.03% V.

  2. 2.

    The increase in the strength of steels 08G2S, 08G2SB, and 08G2SF and the increase of their cold resistance when the final rolling temperature is lowered to 700° are due to refining of the grains and the substructure and also to slowing down of ferrite recrystallization. Raising the final rolling temperature leads to a coarser substructure and intensive recrystallization.

  3. 3.

    The increase in the strength of 08G2S steels microalloyed with vanadium or niobium is higher than for the unalloyed steel due to the precipitation of carbonitrides of these elements. Niobium is more effective in this respect.

  4. 4.

    The notch toughness is highest for 08G2S steel with carbonitride hardening after final rolling at a temperature in the upper range of the austenite region.
