Is stainless steel a good heat and electrical conductor and why?
Electrical and thermal conductivities in metals are related ie good electrical conductors are also good thermal conductors,that’s because in metal the free electrons act as a conducting gas which adds to the conduction of heat by elastic vibrations of the atoms.The purer a metal is the higher is it’s thermal and electrical conductivity;stainless steel is iron with a high fraction of chromium and nickel and this means it has fairly poor conductivity,not even as good as iron(which is no great shakes as a conducting metal).
