The reason why 10403 304 Stainless Steel Wall Mounted with Screw Towel Rack has good rust resistance is mainly due to the presence of sufficient chromium in its composition. Chromium can form a dense chromium oxide film in an oxidizing environment, which can effectively isolate corrosive media such as air and water, thereby protecting the stainless steel substrate from corrosion. In addition, 10403 304 Stainless Steel Wall Mounted with Screw Towel Rack also adds nickel to further improve its corrosion resistance and toughness.
However, in order to further enhance the rust resistance of stainless steel, its surface is usually specially treated. These special treatments include but are not limited to pickling, mechanical polishing, electrolytic polishing, sandblasting and chemical gold plating. These treatments can remove oxides, welding char and contaminants on the surface of stainless steel, improve its surface finish, and enhance its rust resistance to a certain extent.
After the stainless steel surface is specially treated, its touch will vary depending on the treatment method.
Pickling treatment: The stainless steel surface after pickling is relatively smooth and delicate to the touch. However, it should be noted that some chemical reactions may occur during the pickling process, so the treated surface may require further cleaning and passivation.
Mechanical polishing: Mechanical polishing can significantly reduce the roughness of the stainless steel surface, making it smoother and more delicate to the touch. The polished surface presents a mirror-like luster and has a good visual effect.
Electrolytic polishing: Electrolytic polishing is similar to mechanical polishing, and can also make the stainless steel surface achieve extremely high finish. However, electrolytic polishing is more suitable for stainless steel parts with complex shapes, and the polishing efficiency is higher. The treated surface feels smooth and delicate, and has certain anti-fingerprint and anti-oil properties.
Sandblasting: The stainless steel surface after sandblasting presents a frosted texture and feels relatively rough. However, sandblasting can remove minor defects and contaminants on the surface, improve the surface adhesion and uniformity of the coating.
Chemical gold plating: Chemical gold plating is to form a layer of metal plating on the surface of stainless steel to improve its decorativeness and corrosion resistance. The gold-plated surface feels smooth and delicate, and has a certain glossiness and wear resistance.
