How to prevent decorative stainless steel plate rust?

decorative stainless steel plate

It is not strictly true that stainless steel does not rust.Usually we see the stainless steel decorative plate “bright” surface, is also a kind of “rust”, is already born “rust” the chromium oxide.In the manufacture of most stainless steels, varying amounts of chromium are added to the molten iron.So, stainless steel is also a kind of iron chromium alloy, chromium content of about 20 percent.Therefore, when stainless steel is made into products, a dense and stable oxide film of chromium is formed on the surface.It is this thin film of oxide that keeps iron and other easily rusted and oxidized elements from contacting oxygen ions in the air and thus remaining as luminous as ever.

So the problem is to prevent decorative stainless steel plate rust?

First of all, whether 201, 304 and 316 stainless steel, or iron chromium stainless steel, its surface is not suitable for cleaning with chemical detergents, or organic solvents.The reason is that chemical agents will quickly corrosion of the stainless steel surface of the iron and chromium alloy oxide film layer, resulting in internal material contact with the air, causing “rust”, and organic solvents will form organic acids, causing corrosion.Therefore, avoid chemical detergent, organic solvent contact stainless steel surface, can prevent stainless steel decorative plate rust.

Secondly, the storage environment should also be paid attention to.Stainless steel tube or stainless steel plate should not be stored in damp and metal dust containing environment, this may occur chemical battery and electrochemical reaction, so that the product is quickly corroded.
