Abstract
An electromagnetically levitated drop technique has been used to determine the surface tension of 316L stainless steel with impurity additions. By observing the oscillating drop from two directions the drop's frequency spectra can be identified and consistent values of surface tension can be obtained. From the translational modes of oscillation the effect of magnetic pressure on the drop's oscillation frequencies can be accounted for. Surface tension values for 316L stainless steel with various additions of silicon and sulphur are reported. PM/0558
