Electrical Resistivity of Ferrous Alloys and Steels

The TCS Steel and Fe-alloys Database (TCFE) has thermophysical properties included. Below are examples about applications to electrical resistivity. The electrical resistivity thermophysical property data is included starting with version 12 (TCFE12).

The effect of various elements on the electrical resistivity of iron can be calculated.

With the electrical resistivity described for most binary and several ternary systems, predictions can also be made for multicomponent alloys such as austenitic stainless steels.
