Is the 304 stainless steel pipe after wire drawing still anti-rust

Wire drawing is a popular surface treatment technology in the non-ferrous metal industry today, and 304 stainless steel pipe wire drawing is a metal processing technology. People often ask, can 304 stainless steel pipe be rust-proof after wire drawing?
Stainless steel pipe is a kind of corrosion-resistant steel, and its main components are iron, carbon, nickel, chromium and other elements. Chromium will form a layer of high chromium protective film on the surface of stainless steel pipes to prevent further oxidation and corrosion of stainless steel pipes. After the 304 stainless steel pipe is wire-drawn, the chromium-rich protective film on the surface is destroyed, the corrosion resistance of the stainless steel pipe is therefore reduced, and rust is prone to occur.
The common surface treatment of stainless steel pipes is divided into bright surface and matte surface. The brushed matt surface is more wear-resistant than ordinary bright stainless steel, and looks more upscale, so it is deeply loved by the public. Although the 304 stainless steel tube has been brushed, it still has anti-rust effect, but it is brighter than ordinary The performance has indeed dropped compared to the tube.
Although 304 stainless steel pipes still have certain corrosion resistance and rust effect after wire drawing, try not to use them in outdoor exposed places. If they are used indoors, they are not only beautiful, but also rust-proof in indoor environments. If you go outside, pay attention to maintenance. Regularly rub anti-rust oil on the stainless steel pipe, and pay attention to protect the surface of the stainless steel pipe from damage.
