Stainless steel is a metal alloy that combines the most desirable properties of two metals: steel and chromium. Though steel alone exhibits strength, it is subject to corrosion when exposed to moisture. Steel containing at least 12 percent chromium retains its strength and flexibility but gains the attribute of being corrosion resistant. The presence of chromium in stainless steel forms a very thin layer of chromium oxide on its surface. This barrier staves off corrosion, sealing off the stainless steel's internal structure. This feature makes stainless steel ideal for a vast number of applications in industries as diverse as aviation, food preparation, and medicine. Do It! The combination is _________.
