Physical properties of a high manganese austenitic steel Fe-30%Mn-1%C at cryogenic temperatures

In this work, the thermal and magnetic properties of a high manganese austenitic steel, Fe-30 %Mn-1 %C, were examined at cryogenic temperatures. The specific heat capacity, thermal conductivity, and coefficient of thermal expansion (CTE) of the steel were measured from 4 K to 300 K using a physical property measurement system. The magnetization of the steel from 4 K to 300 K was tested by a magnetic property measurement system. The results presented can provide a reference for the potential applications of the high manganese steel in cryogenic components.
