Can stainless steel rust/corrode? Stainless steel is much more resistant to rust, corrosion and staining than other alloy steels, but in some circumstances it is susceptible. In normal atmospheric or water based environments like domestic sink units, saucepans, cutlery and work-surfaces, stainless steel will not corrode however in more aggressive conditions, stainless steel needs to be substituted with a more highly alloyed stainless steel. Steel is made from iron and carbon, whereas stainless steel contains iron, carbon and anywhere from 12 to 30% chromium. Stainless steel can contain other elements such as nickel and manganese, but it is chromium which is the key element which giving stainless steel protection from rust and corrosion
