The corrosion resistance of stainless steel makes it useful for environments where there is a lot of moisture. Many household appliances that deal with water are made of stainless, as are many storage tanks for foodstuffs, water chemicals and gases. Architectural uses for stainless steel are often decorative, for places where metal work will be visible such as panelling, signage and handrails. The automotive industry loves a bit of stainless steel for performance exhausts, heat exchangers and, in high end and performance cars, for panels, fastenings and substructures. There are some fairly obvious uses for stainless steel for applications where hygiene is important including food preparation, chemical applications, medical equipment. Perhaps a less obvious but increasingly important use for stainless is in busy, fast paced environments where regular deep cleaning isn't possible, such as stations and shopping centres.
