After the reform and opening up, my country's economy ushered in rapid development, but in the field of high-end technology, my country is still very backward and often subject to others. Europe and the United States often use their technological hegemony to restrict and monopolize us, hoping to harvest our wealth in this way! After years of investment in technology research and development, Huawei has risen rapidly in high-tech fields such as communications, 5G, and chips, which has completely touched the interests of the United States. Therefore, the United States has imposed all-round sanctions on Huawei. At that time, Huawei's folding screen almost "miscarried" due to Western blockades. Because a key technology was jammed, it was " hand-teared steel ".
In fact, hand-teared steel is just ordinary stainless steel, but ordinary stainless steel needs to be rolled into a very thin state, and must be thin enough to be tear open by hand, and it is about 0.02mm thick to be considered qualified. This requires machine tools with extremely high accuracy and density to complete rolling, so this technology is basically monopolized by the old mechanical powerhouses Germany and Japan.
Hand-killed steel is widely used in key technical fields such as military industry, aerospace, nuclear power, lithium battery, and electronics. With the continuous development of my country's economy and industry, our competitors have more and more demands for steel tearing. So Japan and Germany began to raise prices. A piece of A4 paper-sized hand-teared steel can be sold for 400 yuan, which is more expensive than silver. It is shameless! What’s even more annoying is that in order to limit the development of my country’s science and technology industry, Japan and Germany jointly stipulate that the thickness of hand-teared steel exported to China must be greater than 0.03mm, and the top hand-teared steel less than 0.02mm will not be sold at most!
Faced with the blockade of the West, Taigang Group established a special R&D team and began the independent R&D of hand-killed steel! After thousands of experiments in 2018, Taigang Group finally developed a 0.02mm hand-torn steel, breaking the technological monopoly of Japan and Germany in one fell swoop, completely ineffective in the West.
However, new problems arose later. At that time, Samsung released the world's first flexible folding screen mobile phone, which is considered to be the future development direction of the mobile phone. When Huawei followed up, it found that Samsung used a "flexible steel screen" technology, which means that there was a piece of "hand-torn steel" attached to the back of the flexible screen. It was very thin, but it could provide good support, durability and toughness.
Faced with Huawei being bored, Taiyuan Steel Group once again extended a helping hand, increasing the thickness of the hand-teared steel to 0.015mm in 2020, breaking the record of 0.02mm maintained by Germany and Japan. Our country not only caught up with Germany and Japan in technology, but even achieved "counterattack". The West was so angry that it stamped its feet when it learned about this news!
With this technological breakthrough, Taiyuan Steel Group also won the " China Industry Award " known as the "Oscar" of China's industry. Currently, Taiyuan Steel Group has a market share of more than 70% of the hand-torn steel market in China, and has completely reduced the prices of sky-high products such as "hand-torn steel"! At present, Taigang Group has entered the supply chains of major auto parts manufacturers and the supply chains of domestic mobile phone manufacturers. Moreover, Taigang Group relies on its own technological advantages to carry out in-depth cooperation with BOE and Huawei, and is studying how to maximize the value of Taigang’s product!
Just imagine, if there was no breakthrough from Taigang Group, then mobile phone manufacturers such as Huawei and OV could only import 0.03mm hand-teared steel at a sky-high price of 400 yuan per piece, and then the entire domestic folding screen industry would definitely be left far behind by Samsung. It is no exaggeration to say that Taigang Group is one of the "backers" behind Huawei, and likes such a Chinese company!
