china 316 hot rolled stainless steel pipe
All metal and reaction of oxygen in the atmosphere, the oxide film formed on the surface. It is unfortunate, in ordinary carbon steel formed on iron oxide continued oxidation, corrosion continued to expand, eventually forming holes. You can use paint or metal oxide resistance ( for example, zinc, nickel and chromium ) to ensure that the surface of carbon steel for electroplating, however, as people know it, this protection is only a thin film. If the layer is damaged, the following steel started rusting resistance low corrosion medium such as air, steam, water and chemicals such as acid, alkali, salt leaching medium corrosion corrosion of steel. Also known as stainless acid - resistant steel. In practical applications, often weak corrosive medium corrosion resistance of steel known as stainless steel, and chemical medium corrosion resistance of steel known as acid - proof steel. Due to both differences in chemical composition, which does not necessarily resistant to chemical corrosion medium, while the latter generally have no rust. Depending on the corrosion resistance of stainless steel contains alloying elements in steel. Corrosion resistance of chromium is the stainless steel to obtain basic element, when the amount of chromium in steel when they reach about 1.2, corrosion of chromium and oxygen effects on the media, in a very thin layer of oxide film formed on the surface of steel ( film ), prevents further corrosion of steel substrate. In addition to chromium, a frequently used alloying elements also have nickel, copper, molybdenum, titanium, niobium, nitrogen, to meet the requirements of various purposes on the microstructure and properties of stainless steel.
