The importance of stainless steel surface finishes is in providing an added layer of protection against oxidation, corrosion, rusting, and staining. Finishes can meet design needs, too, leaving aesthetically pleasing appearances for architectural or other decorative applications. Some finishing services may require commercially cleaning and capping or thermocouple cleaning and capping stainless steel material already in service.
