Thermodynamic property of solid MnS–CrS–FeS system was determined based on the combination between thermodynamic properties of liquid MnS–FeS, CrS–FeS, and MnS–CrS–FeS phase determined by the authors and reported phase diagram of MnS–FeS, CrS–FeS and MnS–CrS system. The determined parameters were verified by comparison with experimental results of equilibrium relationship between metal/sulfide in Fe–Cr–Mn–S system at 1793 K. By utilizing the determined parameters, phase equilibria involving sulfide phase in liquid Fe–Cr–Mn–S system was established. According to the phase equilibria information, controllability of MnS–CrS–FeS sulfide phase in typical stainless steel during solidification was evaluated.
