Among the many types of stainless steel, 304L stainless steel has attracted much attention for its unique properties and wide range of applications. As an austenitic stainless steel, 304L stainless steel mainly contains carbon, nickel, chromium and other elements, and the specific proportion of these elements gives 304L stainless steel excellent corrosion resistance. Among them, the chromium element plays a crucial role in 304L stainless steel.

The chromium element forms a chromium-rich protective film on the surface of the 304L stainless steel sheet, which is essential to prevent oxidation and corrosion of the stainless steel. It is because of the existence of this protective film that 304L stainless steel sheet can maintain its original luster and strength under various environmental conditions to prevent rust and corrosion.

However, when the 304L stainless steel sheet is brushed, the chromium-rich protective film on its surface may be damaged. Drawing treatment is a common surface treatment method that can make stainless steel show a unique texture and beauty. However, this treatment will change the properties of the stainless steel surface, so that the original chromium-rich protective film is damaged, thereby reducing the corrosion resistance and rust resistance of 304L stainless steel. Wire drawing oxidation is a kind of surface processing of stainless steel sheet, the surface effect of the sheet is better, and the unique beauty of stainless steel is shown in the form of elevators, screens, sculptures, ceilings and other forms in indoor and outdoor Spaces. However, the effect of wire-drawing oxidation on some stainless steel sheets is positive and negative.

For example, 304L stainless steel sheet, this material itself has excellent corrosion resistance and oxidation resistance. However, after wire-drawing oxidation, 304L stainless steel sheet was degreased and extruded, and some reactions were generated on the surface. At this time, the oxide film of 304L stainless steel plate may not be as stable as before, and its corrosion resistance will indeed be reduced.

On the contrary, drawing oxidation will bring bright surface and matte surface to 304L stainless steel sheet, which are actually more grade surface, many people are more favored. Therefore, we should regularly clean and maintain the stainless steel plate after drawing and oxidation to avoid direct contact with corrosive substances.

In general, 304L stainless steel is praised for its excellent corrosion and rust resistance, but this also requires us to handle and use it correctly. In the pursuit of beauty, we can not ignore the maintenance of its corrosion resistance. Only in this way can we really play the excellent performance of 304L stainless steel, bringing more convenience and value to our life and work.
