Stainless steel is an alloy that is made with at least 10.5% chromium content. It is called stainless because of its natural resistance to rust and corrosion. MC Resources uses type 304 stainless steel (18% chromium, 8% nickel) with a No. 8 mirror finish.
The corrosion resistance and other useful properties of stainless steel are enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen. The chromium forms a passivation layer of chromium(III) oxide when exposed to oxygen. The layer is too thin to be visible, meaning the metal stays shiny. It is, however, impervious to water and air, protecting the metal beneath. Also, when the surface is scratched this layer quickly reforms –it heals itself!
Stainless Steel Cleaning and Maintenance... prevents corrosion and adds to the service life of stainless steel equipment. The goal of a cleaning and maintenance program should be to keep the stainless steel's protective chromium oxide layer intact. This is what prevents corrosion.
