Conclusions

  1. 1.

    Steel alloyed with selenium or selenium+sulfur is superior to steel with sulfur alone in mechanical properties (ductility and toughness) and anisotropy, and is less susceptible to brittle fracture.

  2. 2.

    The improvement of the ductility and toughness of cast and structural sulfur steel after small selenium additions (≤0.15%) is due to the substantial change in the size and distribution of sulfoselenides in microvolumes.

  3. 3.

    Alloying with selenium or selenium+sulfur makes it possible to increase labor productivity and reduce labor costs and costs for cutting tools in turning.
