Why does stainless teel rust? let us first learn to the structure of stainless steel:
Stainless steel is a crystalline solid that is generally composed of atoms in an array of
toys. in addition to iron, it also contains its metal components such as chromium,nikel, and
titanium. Chromium and nickel elements have anti-rust function. which forms a protective film

not damaged, cracked or contaminated by impurities. however, stainless steel will rust if the passive
film is damaged due to improper use or maintenance.
