stainless steel is an alloy of iron with chromium and nickel. In addition to iron and other elements. It is known for its unique combination of properties, including strength, durability, and resistance to corrosion and staining. The addition of chromium to the steel forms a passive oxide layer on the surface of the metal, which helps protect it from corrosion and staining.
The amount of chromium in stainless steel can vary, but it typically ranges from 10.5% to 30%. Nickel is also added to some grades of stainless steel to enhance its corrosion resistance and to improve its ductility and toughness. There are many different grades of stainless steel with varying properties, and each grade is designated by a specific number or letter code, such as 304, 316, or 430.
