Да ли нерђајући челик хрђа?

Нерђајући челик is not rust-free, and its corrosion resistance is affected by the conditions of use and environmental media. The destruction of the protective film will lead to rust. Common causes include electrochemical corrosion, organic corrosion, acid-base corrosion and air pollutant corrosion. It needs to be cleaned regularly, and appropriate materials and products from reputable manufacturers should be selected. Rust removal cream and other tools can be used to treat rust, and safety should be paid attention to during operation.

Хоће ли нерђајући челик зарђати?

When brown rust appears on the surface of stainless steel, some people think: "Is there a problem with the material? Stainless steel will not rust, and rust is not stainless steel."

In fact, this is a one-sided misunderstanding of stainless steel. Stainless steel is not rust-free, but it has stronger corrosion resistance than other materials under the same conditions.

At present, there are still many people who think that as long as it is КСНУМКС нерђајући челик, it will not rust. In fact, whether it is 201, 304 or 316, it will rust under certain conditions!

Зашто нерђајући челик хрђа?

The corrosion resistance of stainless steel will change with the conditions of use and environmental media! For example, in a dry atmosphere, 304 stainless steel is not easy to rust, but if it is in an atmosphere containing a lot of salt, such as in coastal areas, even 304 stainless steel will rust quickly!

Stainless steel actually relies on a very thin, strong, fine and stable chromium-rich oxide film (protective film) formed on the surface to prevent the continued infiltration and oxidation of oxygen atoms to obtain the ability to resist corrosion.

Once environmental factors or other conditions destroy the oxide film, stainless steel will rust! When this protective film is constantly damaged, oxygen atoms in the air or liquid will continue to infiltrate, or iron atoms in the metal will continue to separate out to form loose iron oxide, and the metal surface will continue to rust.

There are many forms of damage to this chromium-containing oxide film, and the more common ones are the following:

1. The surface of stainless steel accumulates dust containing other metal elements or foreign metal particles. In humid air, the condensed water between the attachments and the stainless steel connects the two into a micro-battery, triggering an electrochemical reaction, and the protective film is damaged. This is called electrochemical corrosion.

2. Organic juice (such as vegetables, noodle soup, sputum, etc.) adheres to the surface of stainless steel. In the presence of water and oxygen, organic acid is formed, which will corrode the metal surface after a long time.

3. Substances containing acids, alkalis, and salts (such as alkaline water and lime water splashing for wall decoration) adhere to the surface of stainless steel, causing local corrosion.

4. In polluted air (such as an atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), condensed water forms sulfuric acid, nitric acid, and acetic acid liquid points, causing chemical corrosion.

All of the above situations can cause the destruction of the protective film on the surface of stainless steel and cause rust. So what should we do to ensure that stainless steel does not rust so quickly?

How To Ensure That Stainless Steel Is Bright And Does Not Rust?

To ensure that the metal surface is permanently bright and not corroded, we recommend:

1. The surface of stainless steel must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause rust.

2. It is best to use КСНУМКС нерђајући челик in coastal areas. 316 material has a stronger ability to resist seawater corrosion.

3. The chemical composition of some stainless steel pipes on the market does not meet the corresponding national standards and does not meet the material requirements, which will also cause rust. Therefore, users should carefully choose products from reputable manufacturers.

How Do You Get Rust Off Of Stainless Steel?

If we cannot avoid stainless steel rust, then what can we do to save it? Of course there are. You can refer to the following treatment methods:

Припремите алате:

          Cotton cloth, thick cotton gloves and disposable gloves toothbrush, rust removal paste, super bright water wax (99 wax)

When there is serious rust on the surface of stainless steel, the treatment method after rust

            Remove foreign matter from the surface of the steel pipe and clean the surface with clean water;

            Apply the rust removal paste evenly on the rusted area for about 1-2 minutes;

            Use clean water to remove the paste on the surface and use a disposable toothbrush to scrub the surface;

            Use cotton cloth to clean the surface, then use clean water to clean and wipe dry with cotton cloth;

            Pour a small amount of 99 wax and apply it evenly on the surface of the steel pipe;

            Use cotton cloth to clean the surface.

Опрез:

Rust removal paste is slightly corrosive, and gloves must be worn (disposable gloves + cotton gloves).
