Applications of stainless steel
Medical Technology: Due to its ease of cleaning and low corrosion, stainless steel is widely used in environments where clean and sterile instruments are required, for example, in the production of implants and surgical and dental instruments.
Automotive and transportation: Since Ford introduced stainless steel to the automotive industry in the 1930s, it has been used to produce a wide variety of parts, including exhaust pipes, grills and moldings. In recent years, it has also been used to manufacture structural components.
Building construction: Due to its strength and flexibility, stainless steel has become a key element in the construction sector. It is often used inside for worktops, shelves and railings, and also externally for building cladding.
Food: In the food and catering industry, stainless steel is used to make kitchen accessories and cutlery. Utensils such as knives are made from less ductile grades of stainless steel, while more ductile grades are used to make grills, cookers, pans and sinks.
