Unlike ordinary steel, stainless steel isn't prone to corrosion, rusting, or staining with exposure to water. But this isn't to say it's completely stain-proof. In areas with low oxygen, high salinity, or poor air circulation, stainless steel is vulnerable to staining. Like ordinary steel, stainless steel is a poor conductor of electricity.
