Conclusions

  1. 1.

    The use of a primal charge in the production of steel 30KhGSA helps increase its ductility, reduce the threshold of cold shortness after refinement, and it has practically no effect on the strength properties. The bulk hardenability of steel melted from FSB and SI is poorer than of steel melted from SMP.

  2. 2.

    Steels melted from SI and FSB contain fewer microimpurities than steel melted from SMP, and other conditions being equal, they are less prone to temper brittleness, have higher impact toughness and long-time strength in media causing hydrogenation.
