Stainless steel tube performance changes after drawing

The corrosion resistance of stainless steel tube is very strong, basically will not be affected by the environment, then the Stainless Steel Tube after drawing, its corrosion resistance will change how?

For 304 stainless steel tube, its main constituent elements are iron, carbon, nickel, chromium, etc., of which chromium can form a protective film on the surface of the stainless steel tube to prevent him from being further oxidized, improving the overall corrosion resistance, but after the drawing process, the protective layer will be destroyed, thus affecting the corrosion resistance of the stainless steel tube, resulting in rusting.

Although the drawing will lead to a decrease in corrosion resistance of stainless steel tubes, but usually pay attention to maintenance, it is also able to do rust prevention. After drawing the stainless steel tube as far as possible stored indoors, which can greatly reduce the possibility of rust; if you have to be placed outdoors, you need to regularly wipe the stainless steel tube anti-rust oil, but also to protect its surface is not damaged, which can also reduce the phenomenon of rust.
