Conclusions

  1. 1.

    With combined addition to steel type 30 KhG of microalloying additives (V, Nb, Ti) therefore is a unidirectional, but not additive, effect of these components on material properties, which is connected with formation of complex carbonitrides, redistribution of nitrogen between precipitating carbonitride phases, and a change in the temperature range for their precipitation.

  2. 2.

    An increase in nitrogen content to 0.02% in V-Nb steel increase the effectiveness of microalloying additions providing expansion of the temperature range for the dispersed particle precipitation.
