Is the 304 stainless steel pipe treated with wire drawing still rustproof?

 Stainless steel pipes are corrosion-resistant steel grades, mainly composed of elements such as iron, carbon, nickel, and chromium. Chromium will form a layer of high chromium protective film on the surface of stainless steel pipes to prevent further oxidation and corrosion of the pipes. After wire drawing treatment, the chromium rich protective film on the surface of 304 stainless steel pipe is damaged, resulting in a decrease in its corrosion resistance and susceptibility to rusting.

　　The common surface treatments for stainless steel pipes are divided into bright and matte surfaces. The brushed matte surface is more wear-resistant than ordinary bright stainless steel, and looks more upscale, which is deeply loved by the public. Although 304 stainless steel pipes have been brushed, their rust prevention effect is still good, but their performance is indeed reduced compared to ordinary bright pipes.

　　Although 304 stainless steel pipes have certain corrosion resistance and rust resistance after wire drawing treatment, they should not be used in outdoor exposed areas as much as possible. If used indoors, it is not only aesthetically pleasing, but also sufficient for rust prevention in indoor environments. If placed outdoors, attention should be paid to maintenance. Regularly apply rust preventive oil to stainless steel pipes and be careful not to damage the surface of the pipes.
