Stainless steel is a metal alloy composed of iron, chromium, silicon, carbon, nitrogen, and manganese. It is mainly known for its rust resistance and excellent corrosion resistance, which are key considerations for certain applications. To be recognized as' stainless steel ', the alloy must contain at least 10.5% chromium and no more than 1.2% carbon.
