Pickling stainless steel angle steel advantage

1. 1、Through pickling the stainless steel surface has an average of 10um thick layer of surface is corroded off, the chemical activity of the acid makes the dissolution rate of the defective parts is higher than other parts on the surface, so pickling can make the whole surface tends to be uniform balance, some of the original easy to cause corrosion hidden dangers are removed.
2. 2、Through pickling passivation, iron and iron oxides are dissolved in priority than chromium and chromium oxides, the chrome-poor layer is removed, and the surface of stainless steel is chrome-rich. Under the action of oxidizer passivation, the surface of stainless steel produces a complete and stable passivation film. The potential of this chrome-rich passivation film can reach +1.0V(SCE), which is close to the potential of precious metals, improving the corrosion stability of stainless steel.
