Can stainless steel sheets still be corrosion-resistant after wire drawing?

After the stainless steel sheet undergoes wire drawing, it still retains some corrosion resistance and rust prevention effects. However, compared to stainless steel sheets that have not undergone wire drawing, the performance may slightly decrease.

Currently, the most common surface treatments for stainless steel sheets are bright surface and matte surface. Matte surface stainless steel sheets, after wire drawing treatment, are more resistant to wear than regular bright surface stainless steel sheets. However, the corrosion resistance and rust prevention performance of stainless steel sheets after wire drawing treatment may relatively decrease. Improper maintenance over time may lead to earlier rusting compared to bright surface stainless steel sheets.

Can stainless steel sheets still be corrosion-resistant after wire drawing

Stainless steel is one of the austenitic stainless steels, mainly composed of elements such as carbon, nickel, and chromium. Chromium can form a chromium-rich protective film on the surface of stainless steel sheets, preventing further oxidation and corrosion. The wire drawing treatment can damage the chromium-rich protective film on the surface, leading to a decrease in the corrosion resistance and rust prevention performance of stainless steel sheets. In harsh environments with exposure to wind, sun, and rain, corrosion and rust may occur more easily.

 Before performing wire drawing treatment on stainless steel sheets, it is essential to apply passivation rust prevention treatment. Passivation treatment is based on the thin film theory, suggesting that passivation occurs when metal interacts with the medium, resulting in the formation of a very thin, dense, well-covering passivation film on the metal surface. This film acts as a barrier, preventing direct contact between the metal and corrosive medium and protecting the metal from corrosion.
