description: Duplex corrosionâresistant steels are a relatively new class of steels that combine the best properties of ferritic and austenitic steels. This is achieved by balancing the ferritic and austenitic phases in the steel composition. However, the presence of non-metallic inclusions in steel can negatively affect the properties of the material. Non-metallic inclusions affect the corrosion resistance of the alloy. For duplex corrosion-resistant steels, it is especially important to consider resistance to pitting and stress corrosion cracking. Therefore, it is important to be able to model and control the influence of non-metallic inclusions. In this investigation, the formation of non-metallic inclusions in the melt of duplex corrosion-resistant steel is investigated by thermodynamic modeling. A graph of the dependence of oxygen solubility on the equivalent of pitting resistance, depending on the steel composition, is constructed. The types of inclusions formed in duplex corrosion-resistant steels at different contents of titanium and oxygen, as well as at different contents of deoxidizers: silicon, manganese and aluminum are determined. For high mechanical properties, it is necessary to achieve a high level of deoxidation of steel.
