Stainless steel is the common name for a large group of ferrous alloys that are resistant to rust. Unlike other iron alloys, stainless steel has a stable passivation layer that protects it from air and moisture. This rust-resistance makes it a good choice for many applications, including outdoor, aqueous, food service, and high-temperature uses.
