The interaction coefficient between Al and Sn in molten iron containing high Al was measured using a chemical equilibrium technique. A molten Fe-Al alloy was equilibrated with a molten Ag-Sn alloy in an Al2O3 crucible at 1 823 K. The interaction coefficient of Sn and Al in Fe-Al alloys was measured to be εSnAl = -3.18 while varying the concentration of Al in a range from 0.01-0.17 in mole fraction. The influence of Sn on the deoxidation equilibrium of Al and O was estimated using the above interaction coefficient. The results indicate that under a constant Al concentration, a contamination of several percent of Sn slightly raises the O concentration in high Al steel.
