Stainless steel thin steel sheet will not rust and rot after 30 years

Let's talk about grade 304 first, and its steel grade is 1Cr18Ni9Ti

Grade 201 is a ferritic stainless steel with 5% manganese instead of nickel, and its steel grade is 1Cr17MU6Ni5N

In actual production, China generally takes the middle or lower components to produce its billets according to the requirements of the most downstream enterprises.

Its performance is even more compromised when compared to 304 stainless steel.

According to the use you said, it will not rot after 30 years, but within 10 years, some pitting corrosion will occur, which is pitting rust.

30 years generally looks like this. But all stainless steels have one characteristic that just happens.

Removing the embroidery when rusting can prevent it from continuing to corrode, for example, the spoon used for eating Western food.

Knives are generally made of ni-free 1cr17, and if they are discarded within a year or two, you can see right away.

When rust happens, if it's cleaned in constant use, it's not a problem if you use it for 100 years.

To correct, 201 is the American standard, and the national standard for the national standard is 1Cr17Mn6Ni4N: specific main element content: C<=, Cr16--18

Now the 201 on the market does not meet the requirements of the national standard, the nickel is about 1, which has been calculated, and the chromium content is only 13, the manganese is relatively high, there are more than 7, and I often see about 15.

Because I do metal assays (to detect the chemical composition of stainless steel), I know a lot about this.

Bad 201, three months will be a little rusty.

30 years is too long, I haven't lived that long.

With magnets, it is good to use ten years if you can absorb it.

As long as the thickness does not reach It is very certain that you can see the rust spot in 1 year 2 years obviously rust a large piece 3 years may be pierced by rain Not to mention the domestic 201 stainless steel sheet is a high-grade material on the market 304 or 316 can be used for 10 years is very good If you are afraid of trouble, it is recommended to often paint on the surface is better.

It can be used for 2 months, and you will be thankful. 30 years...

No, it's rust and it's superficial.

The steel plate will rot if it rusts for a long time.

It is a flat steel made by pouring molten steel, cooling it, and pressing it. It is flat, rectangular and can be rolled directly or sheared from wide steel strips. Steel plates are divided according to thickness, thin steel plates < 4 mm (the thinnest mm), medium steel plates 4 60 mm, extra-thick steel plates 60 115 mm.

Steel plate is divided into hot rolled and cold rolled according to rolling.

The width of the sheet is 500 1500 mm; The width of the thickness is 600 3000 mm. Thin plates are divided according to steel types, including ordinary steel, high-quality steel, and alloy steel.

Spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel.

silicon steel and industrial pure iron sheet, etc.; According to the professional use, there are oil drum plates and enamels.

plates, bulletproof plates, etc.; According to the surface coating layer, there are hand but not simple galvanized sheet, tinned sheet, lead-plated sheet, plastic composite steel plate, etc.

The steel grade of thick steel plate is roughly the same as that of thin steel plate. In terms of products, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates and other varieties of pure thick plates, some varieties of steel plates such as automobile girder steel plates (thick millimeters), pattern steel plates.

thickness mm), stainless steel plate, heat-resistant steel plate and other varieties are crossed with thin plates. In addition, not all steel plates are the same, the materials are different, and the places where the steel plates are used are not the same.

With the development of science and technology and industry, higher requirements have been put forward for materials, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear resistance and other special physical and chemical properties.

Steel plates will rust and must be painted to prevent them from rusting. 62616964757a686964616fe58685e5aeb931333337613831

The steel grade of thick steel plate is roughly the same as that of thin steel plate. In all aspects of the product, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates and other varieties of pure thick plates, some varieties of steel plates such as automobile girder steel plate (thick mm), pattern steel plate (thick mm), stainless steel plate, heat-resistant steel plate and other varieties are crossed with thin plates.

In addition, there is a material for steel plates, not all steel plates are the same, the materials are different, and the places where the steel plates are used are also different.

With the development of science and technology and industry, alloy steel has put forward higher requirements for materials, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear resistance and other special physical and chemical properties.

The performance of carbon steel mainly has the following shortcomings:

1) Low hardenability. Under normal circumstances, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.

2) Low strength and yield ratio. For example, the S of ordinary carbon steel Q235 steel is 235MPa, while the S of low-alloy structural steel 16MN is more than 360MPa. The s b of 40 steel is only, which is much lower than that of alloy steel.

3) Poor tempering stability. Due to the poor tempering stability, carbon steel needs to use a lower tempering temperature in order to ensure higher strength when quenching and tempering, so that the toughness of the steel is lowIn order to ensure good toughness, the strength is low when the tempering temperature is high, so the comprehensive mechanical properties of carbon steel are not high.

4) Unable to meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, etc., and cannot meet the needs of special use performance.

There are many types of steel.

304 stainless steel or better medical stainless steel does not rust.

Yes because it's also iron.

Pure steel will not, if it is not a proper steel plate, it may not be!

It shouldn't rust.

Summary. Once the stainless steel shows signs of rotting, it is usually the protective layer on the surface that is damaged or rusted. If not repaired and maintained in a timely manner, the rot may worsen and expand.

Therefore, if the stainless steel is rotten and not treated, it is possible that it will continue to rot. Finding the problem early and taking appropriate measures to repair and maintain it can extend the life of stainless steel and avoid further damage.

Once the stainless steel shows signs of rotting, it is usually the protective layer on the surface that is damaged or rusted. If not repaired and maintained in a timely manner, the rot may worsen and expand. Therefore, if the stainless steel is rotten and not treated with tung tong, it is likely to continue to rot.

Finding the problem early and taking appropriate measures to repair and maintain it can extend the life of the stainless steel and avoid further damage.

Fellow, I really didn't understand, I can be more specific.

If the stainless steel is rotten, it will continue to aggravate and expand the range if it is not treated. Finding problems in advance and fixing them can extend the life of stainless steel and avoid further damage.

Let's talk about grade 304 first, its steel grade is 1Cr18Ni9Ti, and grade 201 is a ferritic stainless steel with 5% manganese instead of nickel.

Its steel grade is 1Cr17Mu6Ni5N

In actual production.

Domestic generally according to the requirements of the most downstream enterprises.

The middle or lower components are taken to produce its billets.

Its performance is in contrast to 304 stainless steel.

It's even more discounted.

For what you say it will be.

It will not rot after 30 years, but some of the pitting corrosion will occur within 10 years, which is pitting rust.

30 years generally looks like this. But all stainless steel has a characteristic of letter search, which is just happening.

Removing the embroidery when rusting can prevent the slippery posture from continuing to corrode, such as the spoon used for dinner.

They are generally made of 1Cr17 without ni.

Within a year or two, if the book is discarded.

You can watch it right away.

To the point rust occurs.

If it is often in use, it is cleaned.

It's not a problem for you to use 100 years.

High-quality steel can also rust, just as people who are in particularly good health can get sick. Rust-proof storage of steel is important. Of course, if it is on the construction site, there are fewer stockpiled goods now, and basically how much is used to procure.

There will also be no serious rust. It still depends on the individual situation.

Steel collapse letter will rust.

However, when the chromium content in the steel is greater than 13%, it will have "stainless steel".

Steel is a general term for an iron-carbon alloy with a mass percentage of carbon between to. The chemical composition of steel can vary greatly, and steels that contain only the carbon element are called carbon steel (carbon steel) or ordinary steel.

In the actual number of production trains, steel often contains different alloying elements according to different uses, such as: manganese, nickel, vanadium and so on.

Steel is an iron-carbon alloy with a carbon content in between. It is usually called steel when combined with iron, and in order to ensure its toughness and plasticity, the carbon content generally does not exceed.

There are many types of steel.

304 stainless steel or better medical stainless steel does not rust.
