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