Why is stainless steel becoming more and more common in life?
Excellent corrosion resistance First of all, stainless steel is mainly composed of iron, chromium, nickel and other elements, of which chromium is the key element of stainless steel corrosion resistance. Chromium can form a dense oxide film on the surface of stainless steel, that is, passivation film, which can prevent oxygen, water and other corrosive media from further eroding the stainless steel matrix. When the surface of stainless steel is slightly corroded, this passivation film is able...
