The extraordinary and unique properties of stainless steels make these alloys exceptional materials of construction in many industries. Although some have perceived stainless steel as a more expensive option on a first cost basis, real prices for stainless steels have been falling dramatically and life cycle cost analysis will often reveal stainless as the most economical option. Its low maintenance, intrinsic value and complete recyclability have also given stainless exceptional environmental credentials.
All stainless steels have a high resistance to corrosion.
This resistance to attack is due to the naturally occurring chromium-rich oxide film formed on the surface of the steel. Although extremely thin, this invisible, inert film is tightly adherent to the metal and extremely protective in a wide range of corrosive media. The film is rapidly self repairing in the presence of oxygen, and damage by abrasion, cutting or machining is quickly repaired. 2 - When scratched, damaged or machined this protective film is denuded exposing the steel to the atmosphere.
