why stainless steel utensils do not rust when exposed to air
Chrome won't rust. That's why it's plated over steel. But any tiny crack or flaw in the chrome plating can allow rust to penetrate the "skin" of chrome and attack the metal beneath. As the chrome barrier is compromised, the rust continues to spread. More and more steel is attacked and breaks down. Stainless steel is (usually) designed so the steel (iron with a bit of carbon) is alloyed with a small percentage of chromium…
