Stainless steel is essentially iron which has been infused with 10% or more chromium. It is good at resisting corrosion and rust through normal wear and tear but occasionally it will dull.
Stainless steel is noted for its hardness and ability to withstand everyday use. To make the flatware shine, chromium is used to form the hard oxide coating on the surface which protects the steel on the inside.
Over time and use and with exposure to elements like dishwashing detergent, this hard protective shell slowly wears down. Frequently the exterior of flatware will dull and no longer retain its luster.
