Stainless steel brackets are generally not prone to rust, but they may still rust under certain conditions.
Below are some reasons that stainless brackets are not prone to rust:
1, Chromized film protection: Stainless steel contains a high level of chromium. Chromium reacts with oxygen to produce a dense chromium oxide coating, which effectively blocks air and moisture, prevents substrate corrosion, and gives stainless steel excellent corrosion resistance.
2, Alloy element enhancement: Adding elements such as nickel and molybdenum further enhances the corrosion resistance of stainless steel.
For example, 304 stainless steel contains 18-20% chromium and 8-10% nickel, which has good corrosion resistance. 316 stainless steel adds molybdenum to further enhance corrosion resistance.
And there are reasons that stainless steel brackets rust:
Mechanical damage: Scratches, wear and tear and other mechanical actions destroy the passivation film, exposing the substrate to the corrosive medium
Chemical corrosion: contact with corrosive substances such as salt, acid, alkali, such as lime water and alkaline water applied during decoration, or long-term exposure to an environment containing sulfide and carbon dioxide.
High humidity and salt: In areas with high humidity or high salt, such as coastal areas, the high salt content in the air can easily form an electrolyte solution on the surface of stainless steel, accelerating corrosion.
Low-quality stainless steel: inferior stainless steel is used as good quality, such as 201 is used as 304, 316
Inappropriate grades: Inappropriate stainless steel grades are selected in specific corrosive environments. For example, using 304 stainless steel in a chlorine-containing environment is prone to pitting corrosion.
In order to maintain the beauty and function of the stainless brackets and extend their service life, correct maintenance is required. The maintenance methods are as follows:
For stainless steel brackets used in home, like stainless steel brackets for shelves, bookcases, TV cabinets, shower benches
Clean regularly, using a soft cloth, sponge and neutral detergent.
Wipe the surface with warm water and a small amount of neutral detergent to remove dust and dirt, rinse thoroughly with clean water to ensure no detergent residue, and wipe dry with a soft, clean cloth to prevent water stains.
For stainless steel brackets used in kitchen, like microwaves, sinks, countertops, Use a stainless steel cleaner to remove grease, stains, and scale, rinse with clean water and wipe dry after cleaning.
For stainless steel brackets used in industries like equipments, pipes, valves, mechanisms, It is recommended to ask professionals to carry out cleaning and maintenance.
Do not use abrasive tools such as steel wool and sandpaper, which will scratch the surface.
Do not use corrosive cleaning agents such as chlorine bleach, strong acids, and strong alkalis, which will damage the protective layer of stainless steel.
