Chinese companies have successfully rolled the world's thinnest stainless steel using domestically produced equipment. According to a report tonight by Science and Technology Daily, domestic enterprise Qingtuo Cold Rolling Technology successfully rolled 0.015 mm ultra-thin hand-shredded steel using localized equipment. This is currently the thinnest stainless steel in the world and a major breakthrough in process technology.
Lan Liang, deputy general manager of the group, said that during the production process, the precision control of production equipment, the purity of steelmaking materials, the technical capabilities of production personnel and the cooperation of the project team will all affect the rolling results.
After summing up experience from hundreds of failures, optimizing the process, and improving operating skills, the R&D team finally achieved the use of domestic equipment to roll hand-shred steel with a thickness of 0.015 mm and a width of more than 600 mm. Hand-tearable steel refers to stainless steel that can be torn by hand. The scientific name is "stainless steel foil". Its thickness is usually only one-quarter of A4 paper and one-sixth of a human hair.
This kind of steel is widely used in the fields of aerospace, electronics, new energy and medical equipment, and can be used in various products from solar panels for aircraft and spacecraft to substrates for folding mobile phone screens.
Hand-shredded steel has the characteristics of excellent material properties, high production difficulty, high equipment precision, weak corrosion resistance, oxidation resistance, heat resistance, etc., and is known as the "Crown Pearl of the Steel Industry". Prior to this, this technology was once monopolized by industrial powers such as Japan and Germany.
The breakthrough in this technology has major implications for the Chinese steel industry. It will allow China to produce more high-quality stainless steel products, which will help to boost the economy. It will also help to reduce China's reliance on imports of stainless steel products.
The breakthrough is also a major boost for China's aerospace and electronics industries. It will allow these industries to produce more high-quality products, which will help them to compete in the global market.
