Why is stainless steel a poor conductor of electricity?
You are correct, stainless steel is a really poor conductor compared to most metals This source lists it as $7496 \times 10^{7}\: \mathrm{\Omega \cdot m}$ 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 through2023年1月18日· This means that when stainless steel is used in applications where electricity needs to be conducted (such as wiring), it can do so efficiently and reliably without corroding or rusting over time However, because chromium makes up only about 10% of stainless steel’s overall composition, its electrical conductivity is lower thanWill Stainless Steel Conduct Electricity?
