Stainless Steel Properties
Stainless steel is chosen when both the properties of steel and corrosion resistance is required. It differs from carbon steel based of the amount of chromium present. Conventional steel rusts readily when exposed to air and moisture creating iron oxide (rust). The chromium in stainless steel forms a passive film of chromium oxide which blocks further corrosion by preventing oxygen from diffusing into the metal. Stainless steel resists corrosion, rust and staining as compared with ordinary steel but, it isn't fully stain proof in environments high in salinity, low oxygen or poor circulation environments. The grade of stainless is chosen based off of the environment it must endure. Generally, the higher the chromium content, the higher the resistance to corrosion.
Technical Plating offers high volume rack and barrel passivation of stainless steels requiring low temperature nitric acid passivation methods.
