Stainless steel earrings are not readily corroded because of the existence of 10% chromium. Although the steel contains small amounts of copper and iron, chromium acts as a resistance blocking any emergence of corrosion. As the name suggests, there will be no corrosion or stains on its surface with stainless steel earrings, with chromium having a significant influence.
