• electrical resistance Why is stainless steel a poor

2020-07-12· You are correct, stainless steel is a really poor conductor compared to most metals. This source lists it as $7.496 \times 10^{-7}\: \mathrm{\Omega \cdot m}$ which is more than 40 times worse than copper.. The reason is that conductivity in metals is high is that metals form a crystal lattice where the outer shell electrons are shared and easily move through the lattice.
