Chromic acid is a powerful oxidizing agent and is a useful compound for cleaning laboratory Chromium steels are types of steel, with which iron can be alloyed with chromium. Colloquially the term is often used interchangeably with the word stainless steel. In principle, chromium does not have to be necessarily contained in stainless steel, but chromium is one of the most common alloying elements in stainless steel grades and is contained in most commercially used stainless steel grades. Outside this rainbow of chromium compounds, chromium helps prevent a particularly undesirable colour: rust brown. In corrosion-resistant, or "stainless", steels, at least 11% of its mass is chromium.
