Stainless steel is a highly durable metal, allowing it to withstand the wear and tear of everyday activities. The hard metal resists scratches and corrosion thanks to an invisible layer of chromium that prevents tarnish and rust from forming on stainless steel also keeps it from reacting to many other chemicals. Environments that contain a high chlorine or salt do not affect stainless steel.
