Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air.
The word 'stainless steel' itself says the steel that doesn't get stain or rust. Stainless steels are highly stable material under different environmental conditions. Mainly four types of stainless steels are used in pharmaceutical equipment manufacturing, 304, 304L, 316 and 316L.
General principles for selection of stainless steels Introduction. Stainless steels are defined as iron alloys with a minimum of 10.5% chromium. Other alloying elements are added to enhance their structure and properties, but fundamentally, stainless steels are considered for selection as steels with corrosion resistant properties.
The principle of stainless steel anti-rust property. All metal contact oxygen and react with it, to form oxide film on metal surface. Unfortunately, ferric oxide on common carbon steel surface keeps going on oxidizing and enlarge the area of rust, finally the rusted hole come out.
The SAE steel grades system is a standard alloy numbering system for steel grades maintained by SAE International. In the 1930's and 1940's, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly.
