High-end electronic products including mobile phones will become easier to make, lighter and more durable, thanks to China Baowu's new steel products. On May 12, on the occasion of the first anniversary of General Secretary Xi Jinping's investigation tour to China Baowu-TISCO, two new products of the company, i.e. the 0.07mm ultra-flat stainless steel precision strip and the surface-texture-free stainless precision strip, were launched in Shanxi Taigang Stainless Steel Precision Strip Company.
One year ago, General Secretary Xi Jinping, who was investigating in Shanxi Province, visited Shanxi Taigang Stainless Steel Precision Strip Company and made an important speech, encouraging the company to make persistent efforts in scientific and technological innovation, especially in the field of stainless steel, and take new and greater steps in supporting the development of advanced manufacturing industry. Over the past year, the company staff has kept in mind the general secretary's entrustment, implemented the innovation-driven development strategy to new steel materials that are key to the development of advanced manufacturing industry, and launched a series of high-precision and special products recognized by the market, such as 0.015mm "hand-tearable steel", fast reactor 316H stainless steel and thin silicon steel sheet.
The 0.07mm ultra-flat stainless steel precision strip, one of the twin protagonists in the global debut ceremony, is the raw material for backlight plate, a key structural component of mobile phones. With the rapid development of 5G communication technology, the lightweight of backlight materials has become a new trend, which demands urgently a lighter backlight material. Meanwhile, mobile phone producers at home and abroad put forward more demanding requirements on flatness, strength, magnetism, etc. of stainless steel strips for internal components such as mid-plane and camera base. Aiming at the market opportunity, TISCO engineers and R&D staff spent one year on tackling technological problems and successfully developed a complete set of production process. The product, with thickness of 0.07mm, flatness superior than 0.1mm/m and strength above 1,200MPa, has been put into commercial production amid a promising market prospect.
Stainless precision strip steel with non-textured surface, the other of the twins, is an advanced stainless steel material with extremely high surface grade. It is developed and produced to solve the resolution problem of the tiny QR codes sprayed on internal structural parts and components of high-end electronic products. As a replacement of conventional cold-rolled stainless steel, the new material with texture-free surface enables more identified QR code for intelligent manufacturing. It greatly reduces the surface roughness and glossiness difference, and solves the identification problems of electroplating and spraying parts in the process of strip deep processing. At present, the new material has passed the product application test of a well-known mobile phone producer and is in mass production.
Mr. Wei Yao, member of the Standing Committee of China Baowu Party Committee, attended the debut ceremony and unveiled the new products together with the chief engineer of China Baowu and leaders of TISCO. Other attendees include heads of business segments and functional departments of China Baowu Group, as well as Mr. Gao Xiangming, the Party Secretary and Chairman of TISCO, Mr. Wei Chengwen, the General Manager and Deputy Party Secretary of TISCO, and heads of relevant TISCO units.
