Many people think that stainless steel does not rust because it does not contain iron. However, this is only partially true. Stainless steel does have iron, but it also contains chromium. The chromium forms a thin layer of oxide on the surface of the steel, which prevents oxygen and water from reaching the iron beneath. This is what makes stainless steel so resistant to corrosion.
Stainless steel is an alloy of iron, chromium, and other metals. The chromium forms a thin layer of oxide on the surface of the steel, which prevents oxygen and water from reaching the iron beneath. This is what makes stainless steel so resistant to corrosion.
The higher the percentage of chromium in the alloy, the more resistant the steel will be to corrosion. The minimum chromium required to form this protective oxide layer is 10.5%. Most stainless steels contain at least 18% chromium.
Stainless steel also contains other metals, such as nickel and molybdenum. These metals add to the corrosion resistance of stainless steel by forming their protective oxide layers on the surface of the metal.
So now you know why stainless steel does not rust! It’s all thanks to that magic ingredient called chromium. If you ever need a durable, corrosion-resistant metal, remember that stainless steel has your back.
