Abstract
The mechanical properties, chemical composition, microstructure, and nonmetallic inclusions in steel 20GL subjected to out-of-furnace treatment in an AKP installation (furnace-ladle unit) and melted by the standard process are studied. The effect of the out-of-furnace treatment on the content of sulfur, on the contamination of the metal with nonmetallic inclusions, and on the impact toughness of specimens with U-and V-notches at a test temperature of + 20 and − 60°C is determined.
