Conclusions1.Small selenium additions (0.04–0.08%) have a substantial effect on the nature, morphology, and dispersity of nonmetallic inclusions and thus the mechanical, technological, and operating properties of structural steel.2.Selenium additions, leading to globularization of nonmetallic inclusions, reduce the anisotropy of the ductility and fracture toughness and also susceptibility to brittle fracture (tested with transverse samples).3.Microalloying with selenium reduces the loss of…
