Stainless steel is an iron alloy containing chromium and carbon – elements that contribute to the formation of a surface layer, a protective layer against corrosion, also known as a passive layer with a tendency to self-regenerate. This process is responsible for the steel’s corrosion resistance. Due to this process, stainless steel can be considered many times more corrosion-resistant than ordinary steel. Given the aforementioned properties of stainless steel in today’s chemically aggressive industrial environment, which affects the speed and quality of the self-forming surface layer, it should be emphasized that stainless steel requires systematic maintenance and care to preserve its aesthetic appearance and corrosion resistance (the method of maintenance and care is described in the technical and operational documentation of the devices, in the ‘Maintenance’ section).
