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.
All stainless steels have a high resistance to corrosion.
Some grades will resist scaling and maintain high strength at very high temperatures, while others show exceptional toughness at cryogenic temperatures. The majority of stainless steels can be cut, welded, formed, machined and fabricated readily. The cold work hardening properties of many stainless steels can be used in design to reduce material thickness and reduce weight and costs. Other stainless steels may be heat treated to make very high strength components. Aesthetic appeal Stainless steel is available in many surface finishes.
