There are a large number of stainless steels produced. Corrosion resistance, physical properties, and mechanical properties are generally among the properties considered when selecting stainless steel for an application. A more detailed list of selection criteria is listed below:

* Corrosion resistance
*Resistance to oxidation and sulfidation
* Toughness
*Cryogenic strength
*Resistance to abrasion and erosion
*Resistance to galling and seizing
*Surface finish
*Magnetic properties
*Retention of cutting edge

* Ambient strength
* Ductility
* Elevated temperature strength
* Suitability for intended cleaning procedures
* Stability of properties in service
* Thermal conductivity
* Electrical resistivity
* Suitability for intended fabrication techniques

Corrosion resistance is commonly the most significant characteristic of a stainless steel, but can also be the most difficult to assess for a specific application. General corrosion resistance is comparatively easy to determine, but real environments are usually more complex. An evaluation of other pertinent variables such as fluid velocity, stagnation, turbulence, galvanic couples, welds, crevices, deposits, impurities, variation in temperature, and variation from planned operating chemistry among others issues need to be factored in to selecting the proper stainless steel for a specific environment.
