On August 9, a truck load of 600 kg of stainless steel with a thickness of only 0.02 mm was shipped from China to Germany, which is currently the thinnest stainless steel in China.
This stainless steel with a thickness of 0.02 millimeters and a width of 600 millimeters is also called "hand-tipped steel". The reporter saw in TGJT's special precision strip steel company that "hand tearing steel", which is only a quarter of the thickness of A4 paper, was easily torn in the hands of staff.
This is another self-developed product that can replace imported products after China's “pen tip steel” in 2017. According to the Manager of TGJT Special Precision Strip Steel Company, looking at the large steel companies in China, the 0.02 mm “hand-tipped steel” developed by TGJT is currently the thinnest stainless steel in China. Process control is difficult and has long been monopolized by countries such as Japan and Germany.
Liao Xi, the inspection supervisor of TGJT Special Precision Strip Steel Company, told reporters that the size range of stainless steel precision strip steel is generally between 0.05 and 0.5 mm, and below 0.05 mm is called stainless steel foil. At present, most of the soft stainless steel in the market is 0.05 mm. The 0.02 mm stainless steel developed this time is a cutting-edge product higher than the industry standard. This ultra-thin stainless steel is mainly used in aerospace, petrochemical, automotive, electronics, home appliances, Computer and other fields.
As early as the establishment of the TGJT Special Precision Strip Steel Company in 2008, the production of the thinnest stainless steel was regarded as a research and development goal. After numerous failures, a small amount of 0.02 mm stainless steel was developed in 2017, and reached mass production level not long ago.
In 2017, the “pen-tip steel” developed by TGJTT's special steel caused heated public debate, and “Made in China” attracted attention at home and abroad. The advent of the thinnest stainless steel not only broke the long-term foreign monopoly, but also improved the manufacturing process of stainless steel foil to the world's leading level.
According to Wang Tianxiang, not only is “hand tearing steel”, TGJT`s cutting-edge technology has always been the support of world science and technology. At present, the company has cooperated with many enterprises to develop hydrogen fuel cell passenger cars, flexible solar photovoltaic power generation, ocean detection , New materials in new lithium battery coatings and other fields.
