The Magnetic Character of Austenitic Stainless Steels
The results of a series of low-temperature magnetic and calorimetric studies relating to the magnetic character of austenitic stainless steels are summarized and discussed. Twelve members of both the AISI 300 series and the proprietary Nitronic series, as well as other alloys, have been investigated from time to time in collaboration with J. C. Ho , M. P. Mathur , R. D. Smith , R. L. Cappelletti , H. W. King , H. M. Ledbetter [5,6], and S. C. Hart . The AISI 300 series alloys generally exhibit a superparamagnetic susceptibility temperature and field dependence superimposed on a background susceptibility whose temperature dependence passes through a cusp at low temperatures. The Nitronic alloys show a cusp but no superparamagnetism.
