What is the use of ultra thin stainless steel foil? After more than 700 failures in China, there are an endless stream of buyers

If the price of a kind of steel is more expensive than gold, would you believe it? In fact, there really exists such steel in the world. In fact, it is a kind of special steel and a kind of steel with high-tech content. It is called ultra thin steel. Because its thickness can reach 0.02mm, only 1/4 the thickness of a piece of A4 paper, it is very thin and can also be directly torn by hand. Therefore, this kind of steel is also called "stainless steel foil".

Recently, the "stainless steel foil" developed by our customer TISCO has attracted great attention on the Internet. At present, the market price of hand tearing steel is very expensive. After Chinese enterprises have mastered the production process of this kind of steel, the price of a piece of hand tearing steel that reaches the size of A4 paper can reach RMB 400, and the price per gram can reach RMB 5~6, which is more expensive than that of silver. Moreover, this is the price after Chinese enterprises have mastered the relevant production process.

However, before China had mastered the relevant technology, only a few enterprises in Germany and Japan could produce this kind of steel, that is, they were in a monopoly position. Of course, they would not miss the opportunity to make a lot of money, raising the price of this kind of steel very high, even exceeding the price of gold. It can be said that the added value of technology is too high.

So what is the use of stainless steel foil?

In the military field, because the thickness of hand tearing steel is very thin, the shielding performance is very good, and its weight is relatively light, it can be used to shield signal interference. In modern wars, a large number of Seiko products are equipped with electronic equipment, so it is inevitable for the hostile parties to launch electronic information warfare. With the hand tearing of steel, they can have a great advantage in electronic information warfare, and may become a decisive factor in the war.

Photovoltaic industry can be developed not only on the ground, but also in space. Because the spacecraft needs solar panels, of course, this kind of equipment becomes lighter and can be folded, which will bring great convenience to the launch of the spacecraft. At the same time, hand tearing steel has strong corrosion resistance, oxidation resistance and heat resistance, and is also an ideal material for making solar panels. Therefore, the role of hand tearing steel in this regard can not be ignored.

In fact, stainless steel foil can also be used as a more accurate pressure sensor diaphragm; In the field of new energy, hand tearing steel can also be used as protective material for lithium-ion batteries; Even in the field of nuclear power, it can play a great role because it has good shielding and heat resistance, and its weight is relatively light. It can be used to make protective clothing with high-strength performance.

However, it sounds as if these performances are not closely related to our daily life, so here are some examples that are closely related to our daily life. Mobile phones should be an indispensable tool in our daily life. With the development of mobile phones, some enterprises have also developed mobile phones with folding screens in recent years. In fact, the key material is hand tearing steel, because it is a kind of flexible screen steel, which can withstand 200000 folds without deformation and fracture.

Of course, the folding here does not mean folding after folding, but unfolding after folding and then folding. If the average mobile phone consumer folds it 50 times a day, it can be used for about 10 years. In the past 10 years, mobile phones have been upgraded for a long time. This shows that the quality of this hand torn steel as the material of folding screen mobile phones is really very good.

Since 2016, our client, Taiyuan Iron and steel company, has set up a scientific research team, which has conducted more than 700 tests and failed. Finally, a successful method was selected from more than 40000 kinds of arrangement and combination of binding rollers. The 30 person team has overcome 175 equipment problems and 452 process problems. It took more than two years, and about one test failure a day on average. However, the scientific researchers have withstood these pressures, Finally, a stainless steel foil with a thickness of 0.02mm and a width of 600mm was successfully produced in 2018.

On this technical issue, it has quickly become one of the world's leading enterprises. Although German and Japanese enterprises can produce stainless steel foils, they can produce stainless steel foils with a narrow width, that is, the thickness is 0.02mm and the width is 400mm. This is not much different from Chinese enterprises in thickness, but the width is much worse than China's 600mm. Because if applied, the 600mm width can cut out more shapes. Of course, the application range is relatively large, so the advantage will be more obvious.

To sum up, the hand tearing steel has a wide range of applications, which can be widely used in the aerospace field, as well as in some military equipment. It is also used to provide assistance for folding screen mobile phones. There is no doubt that hand tearing steel has become a high-end product in steel and has been widely used in high-tech products.

LEBON was very lucky to cooperate with TISCO for the first time in 2012 to jointly develop the first pneumatic direct connected 8K mirror machine in China that has been protected by the national invention patent so far, so as to upgrade the process of their new products. Up to now, both of us have maintained close cooperative relations. We believe that LeBon and TISCO will continue their sincere cooperation, work together for win-win results and create more brilliance.
