stain·less steel | ˈstān-ləs stēl
noun
A steel alloy including chromium and sometimes another element such as nickel or molybdenum
Stainless steel is an alloy of steel that includes chromium and other elements that are designed to increase durability including nickel and molybdenum. The resulting alloy is nearly immune to common elements that impact many metals such as rust and corrosion as a result of oxidation, moisture, and exposure to other elements. Stainless steel is not commonly used in jewelry except in watches, but may also be used as part of men’s wedding bands to provide a durable alternative to some other types of metals.
