Stainless steel in metallurgical definition is a steel that contains ~14% or more Chromium. Other alloying elements such as Nickel can also improve steel's stain resistance properties. The amount of free Chromium, i.e. not tied up in carbides determines steel's stain resistance ability. Higher carbon content leaves less free Chromium in the
