201 stainless steel rusts, what can be replaced?

Here I need to correct you, 201 can't be called stainless steel, people in the industry call it stainless iron.

Its corrosion resistance is not stainless steel grade.

At present, in order to prevent corrosion, the commonly used materials are galvanized, aluminized, aluminum-zinc, magnesium-aluminum-zinc, and stainless steel.

Stainless iron is between galvanized and aluminum-zinc and is a type of stainless iron that is less resistant to corrosion.

Stainless steel has 200 series, 300 series, 400 series.

The 200 series is not actually stainless steel at all.

If high corrosion resistance is required, such as in a strong acid environment, only 300 series and 400 series can be selected.

In other environments, atmospheric corrosion, alkaline corrosion, seawater corrosion, you may wish to contact me to try magnesium aluminum zinc plating material. (Developed by Nippon Steel in Japan).

Stainless steel is not necessarily not embroidered, and the thin plate does not rust mainly by a thin passivation film on the outside to prevent continued oxidation!

When the surface of stainless steel has abrasions, scars, exposure to the atmosphere, rain, and some kind of medium, it is easy to rust!

In addition, the higher the chromium and nickel content in stainless steel, the less likely it is to rust, 201 nickel containing about 17% chromium belongs to nickel-saving stainless steel, which is easier to rust than 304 18 chromium 8 nickel... So it is advisable to adopt 304! It is suitable for most occasions, but it is necessary to pay attention to the surface not to scratch, etc

Hope, give a point!

Such as equipment, facilities are not easy to replace. Or if you want to save money, remove the rust from the existing rusty parts and wax them. It will solve the rust problem of 201.

Regular scrubbing is important. It is better to use 304 conditionally. There will be no rust both indoors and outdoors.

I usually use 201 indoors, not humid places, indoor only use 304Save money.

201 stainless steel will rust.

The meaning of stainless steel is not that it will not rust, but that it is not easy to rust, the surface of stainless steel has a very thin, strong and fine and stable chromium-rich oxide film, and the reason why stainless steel is rust-proof is that this layer of oxide film prevents oxygen atoms from penetrating into the oxidation reaction and causing rust. The surface of stainless steel is damaged and oxidized when it comes into contact with air, resulting in a rust layer, which is what we call rust.

Due to the limited corrosion resistance of 201 stainless steel, there are very strict requirements for the use environment, if it is in a relatively dry and normal use environment, the service life of 201 stainless steel can generally reach 5-8 years, and the service life will be longer if it is properly maintained; But in the case of harsh environment, being able to insist on 2 years proves that the quality of this piece of 201 stainless steel is very good.

201 development of stainless steel

The 201 series stainless steel was first developed in the United States during World War II as a substitute for the 300 series stainless steel. At that time, due to the war, nickel as a strategic material was strictly controlled by the relevant countries, and the amount of nickel in the United States was seriously insufficient. In order to solve the problem of stainless steel production and production in the case of a serious shortage of nickel, the United States has developed this new steel series.

The production of 300 series stainless steel is no longer restricted by the shortage of raw materials, so the 201 series has not been greatly developed. After returning to India, several Indians who participated in the development of 201 series stainless steel brought back to India the stainless steel varieties of 201 series steel developed in the United States, starting from the fact that India is relatively rich in manganese resources and lacking nickel resources.

Will it rust later with salt and white vinegar?

No, it won't. What's wrong with the dear.

201 stainless steel rust, remove the rust on the 201 stainless steel, pour some baking soda into the rusty position, and evenly apply the baking soda to the rusty part, the specific operation steps are as follows:

1. Pour some baking soda over the rusty area.

2. Apply baking soda evenly to the rusty area.

3. Pour some white vinegar into the rusty parts.

4. Stir together the baking soda and white vinegar and let stand for 2 minutes.

5. Pour in some alcohol.

6. Use steel wool balls to rub back and forth.

7. Finally, wipe it clean with a paper towel and the operation is completed.

201 stainless steel will rust.

201 stainless steel will rust in certain environments, such as soaking in salt water, but it is very difficult to rust in daily environments. Stainless steel is not easy to rust because it contains nickel, and compared with 304 stainless steel, 201 stainless steel will have less nickel, so it is more likely to rust than 304 stainless steel.

What are the advantages of stainless steel?

1. Because the surface of stainless steel generally undergoes polishing, the surface has a very translucent color. When you touch the stainless steel material with your hands, you will find that the feel is particularly delicate. In addition, stainless steel is not prone to rust, so it retains its shiny appearance even after a long period of use.

2. There is no harmful substance such as lead in stainless steel, so the faucets on the market are generally made of stainless steel. Because the stainless steel faucet can effectively control the quality of the water, and it is also very clean. At the same time, stainless steel does not need to go through this link of electroplating in the production process, so it generally does not cause harm to the environment.

3. Finally, stainless steel items are also very durable. Relevant tests have proved that stainless steel generally has a service life of decades or even hundreds of years. And there is no special maintenance required in the process of using stainless steel.

Stainless steel is not not rusty is not easy to rust, stainless steel is not easy to rust ability is mainly based on nickel element. The nickel element of 201 stainless steel is 0%, and the nickel element content of 304 stainless steel is 8%, which is compared with 304 stainless steel. 201 stainless steel is definitely prone to rust.

202 stainless steel contains 4% nickel, which is much stronger than 201.

Extended Information: How to Prevent 201 Stainless Steel from Rusting.

1.In the humid air, the condensation between the attachment and the stainless steel connects the two into a micro finger battery, which triggers an electrochemical reaction and destroys the protective film, which is called electrochemical corrosion.

2.The surface of stainless steel adheres to organic juice (such as melon vegetables, noodle soup, phlegm, etc.), which constitutes organic acid in the presence of water and oxygen, and the corrosion of organic acid on the metal surface for a long time.

3.The surface of stainless steel contains acids, alkalis, and salts (such as alkaline water and lime water splashing on the decoration wall), which causes local corrosion.

4.In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), condensation will form sulfuric acid, nitric acid, and acetic acid solution spots, causing chemical corrosion. Branching.

Summary. Whether it will rust in the use of 201 years will depend on the use environment, in the ordinary indoor environment 201 stainless steel for decades is no problem, such as the common stainless steel baseboard, stainless steel decorative strips are mostly used 201 stainless steel, because it is rarely exposed to water or humid air, and it will not rust for a long time. If it is in an ordinary outdoor, it is no problem to use qualified 304 stainless steel for decades, but if it is 201 stainless steel, it may rust in a month or two, if it will rust faster at the seaside, if it is not submerged in 304 and 201 seawater, 316 should be used.

201 stainless steel is not the best stainless steel, and it is not surprising that it rusts in some situation.

Stainless steel is divided into a variety of types, suitable for different application environments, even the same kind of stainless steel, in the same environment, the anti-rust ability is also different, because the main elements in stainless steel CR and Ni Ti content is different, will also have a difference in the anti-rust ability, and the cost will be significantly different.

At present, many small manufacturing enterprises reduce cost requirements, more and more relaxed on product design materials, from good stainless steel to general stainless steel, some enterprises even switch to medium carbon steel, the cost is low, but the product life is reduced linearly, which is not controllable by technology!!

Most of the 200 series stainless steels sold in the Chinese market have almost no control of sulfur and carbon content according to the national standard, and manganese (and nitrogen) replaces some or all nickel to produce austenitic stainless steels with lower nickel content.

The disadvantage of this series of materials is: the chromium content of 18 and the low nickel content are not balanced and form ferrite, for this reason, the chromium content in the 200 series stainless steel is reduced to 15 16, and in some cases to 13 14, and its corrosion resistance is not comparable with 304 and other similar steels.

201 stainless steel can rust, especially in humid environments.

In a dry environment, the use of 201 stainless steel is usually not rusty. However, if this type of steel is used in a corrosive environment, it is not possible to avoid the rusting of the steel. However, the surface treatment of this kind of steel is better, so the ability to resist rust is relatively strong.

At the same time, different brands of steel will have different degrees of rust in use.

Stainless steel has good performance, long life, and more importantly, beautiful appearance, which can keep it bright as new for a long time. When people are buying 201 stainless steel, they will consider whether this steel will rust. In fact, whether the steel will rust depends on the application environment, and the different application environment will cause the steel to rust or not.

Compared to ordinary steel, 201 stainless steel is very unlikely to rust, and people can buy this steel with confidence. Of course, when purchasing, we should pay attention to the brand, and the different brands will play a certain role in use.

Metals rust and non-rust are relative, there can be no metal that is absolutely rust-free, and even gold and platinum, which are the least likely to rust, will corrode and rust when they encounter solutions with particularly strong metal dissolving capabilities, such as aqua regia.

Stainless steel is also rusty, the number represents the performance grade of stainless steel, that is, the content of stainless steel containing other alloys, 304 stainless steel is currently the most widely used stainless steel, and the rust resistance is much stronger than 201.
