摘要：

The problem of improving the quality of centrifugal pipes made of austenitic stainless steel is considered. It is proposed to tap ferro-titanium in a furnace under slag, after its deep deoxidation by REM-containing additive for receiving such pipes with high mechanical and service properties. Before tapping the melt from the furnace, the melt must be processed by nano-dispersed titanium carbonitride in the modifying briquette composition. Implementing the above conditions allows increasing the tensile strength of cast metal by 10-15%, plasticity by 30-45% with increasing resistance to intergranular corrosion (IGC) in the casting section.
