Steel with a chromium content of more than 10.5%, as well as various other elements in smaller quantities, is considered to be stainless. In combination with oxygen chromium forms a thin, sealed, fixed-adhering, chromic-oxide layer – the so-called passive layer. It is exactly this passive layer which is responsible for the resistance of the material. Due to its corrosion resistance, the metal is used for example for washing drums.

Rust-resistant stainless steel can be very well compared to anodised aluminum with regard to its properties. If the exterior skin of the material is impaired, the material and its surface mostly suffer damage.

Stainless steel is preferred in clean and sterile environments as it is simple to clean and does not easily corrode. Stainless is used in the production of a wide range of medical equipment, including surgical and dental instruments.

Due to its strength, resistance, and flexibility, stainless steel application has become a vital element of the building trade. It is commonly featured in the interior on countertops, backsplashes, and handrails, and is also used externally in cladding for high impact buildings.

The aviation industry also has a preference for stainless steel. It is used in various applications including the frames of aeroplanes because of its strength and ability to withstand extreme temperatures. It can also be applied in jet engines as it can help prevent against its rusting In the food and catering industry, stainless steel is used to manufacture kitchen accessories, cookware, and cutlery. Utensils such as knives are made using less ductile grades of stainless steel. The more ductile grades are used to make grills, cookers, saucepans, and sinks.
