steel research international, Volume 95, Issue 11, November 2024.The study combines a thermodynamic equation with a kinetic model to predict nitrogen content (0.150–0.400%) at the end of argon oxygen decarburization process when producing nitrogen‐alloyed stainless steels. The adjustment of nitrogen content is achieved by blowing nitrogen–argon mixtures through blowing, and the model successfully predicts this ...
