description: The work is devoted to studying the effect of the amount of REM acting as modifiers on the performance properties of duplex steel. A hot physical experiment was conducted for smelting and casting duplex corrosion-resistant steel of type S32750. The modification of the cast structure during the introduction of REM is shown. The transformation of nonmetallic inclusions with the addition of REM has been studied by optical and electron microscopy methods. It is shown that there is an optimal concentration of rare earth metals, at which contamination with inclusions is minimal due to favorable conditions for their removal, and with a further increase in consumption increases due to the coagulation of a large number of refractory oxides. The corrosion and mechanical properties of the studied duplex steel are significantly improved when treated with rare earth metals. Based on the obtained results on operational properties, the optimal amount of REM introduced for modification of inclusions is 0.05% (0.65Ce+0.35La).
