TISCO presided over the formulation of the national standard "Stainless Steel Precision Foil" and passed the review by the Steel Standards Committee
On September 25, 2021, the "Stainless Steel Precision Foil" national standard developed by Shanxi Taigang Stainless Steel Co., Ltd. and other units was approved by experts from the National Steel Standards Committee and will be officially released and implemented after being submitted to the National Standardization Management Committee. .
After the national standard-setting project plan for "Stainless Steel Precision Foil" was issued, TISCO immediately organized domestic experts who have long been engaged in the research, production and use of stainless steel precision foil to form a standard preparation team. According to the current production status and future development trends of precision foils at home and abroad, the compilation team combines the actual production of domestic enterprises and the needs of downstream key customers, according to the characteristics of precision foils and the characteristics of related application fields, after several months of hard work, the formation The draft of the national standard for soliciting opinions and on this basis have been extensively solicited opinions from the society. At the national standard review meeting organized by the Steel Plate and Steel Strip Sub-Technical Committee of the National Steel Standards Committee, the national standard passed the expert review after presentation, discussion, and questioning.
Due to the extremely thin thickness of stainless steel precision foil (thickness less than 0.05mm), the performance that users pay attention to is very different from that of traditional stainless steel cold-rolled plates, such as surface cleanliness, surface condition, shape measurement, performance testing, etc., especially the The dimensional tolerance, three-point difference, and the same stripe that the standard focuses on have reached the order of micrometers, and the inspection method has even introduced optical instruments. At the same time, the standard draws on the detection methods of non-ferrous metal foil, coating industry, paper industry, etc., introduces the detection of puncture strength, surface wetting angle, and effectively takes into account the electronic, medical, coating and other industries for ultra-thin materials. The performance requirements ensure the applicability of national standards to the greatest extent.
Although the production history of precision stainless steel materials in my country is short, with the rapid development of the domestic manufacturing industry represented by the electronics industry, the demand for this type of material in the domestic market has increased exponentially. However, various product standards at home and abroad have There have been no corresponding regulations for ultra-thin products. The formulation of the national standard of "Stainless Steel Precision Foil" standardizes the technical requirements of this type of product, builds a unified platform for manufacturers and users, and also fills in the gaps in the national standard in this field, making my country's stainless steel The strip standard system is becoming more perfect. In the next step, the compilation team will compile the English version of the standard to lay a solid foundation for our country's advanced materials to enter the world.
