The only alternative import in the country! Batch stable supply of SUS630 stainless steel cold rolled sheet in Taiyuan Iron and Steel Co., Ltd.

After nearly three years of system research and continuous improvement, TISCO has achieved stable batch supply of precipitation-hardened SUS630 stainless steel cold-rolled sheet products, and has become the only enterprise in China that can provide such products. This product solves the problem of "sticking neck" of key basic materials in China's electronic circuit industry, and helps China's electronic circuit printed circuit board (hereinafter referred to as "PCB") industry to move forward to the high end.

PCB is the carrier of integrating electronic components and realizing control function, commonly known as "the mother of electronic products". PCB is the focus of scientific and technological competition in various countries and belongs to the national strategic technology field. Downstream applications cover important fields such as 5G, automotive electronics, consumer electronics, industrial control equipment, medical electronics, aerospace and military products, and is the core content of "made in China 2025". In recent years, China has made great efforts to develop the PCB industry. At present, it has become the largest PCB production area in the world, and the products are gradually upgraded from low-end to high-end.

Precipitation hardening stainless steel SUS630 is widely used in hot lamination of printed circuit boards. It is one of the indispensable basic materials in electronic circuit industry. Its quality level has the most direct impact on the safety and stability of electronic products. Production technology and procurement channels have been mastered by foreign countries for many years. With the rise of high-tech industries such as 5G, Internet of things, smart medicine, autopilot and wearable devices, the demand for SUS630 materials in the electronic and circuit industry has increased significantly, and the problem of "neck jam" has become increasingly prominent.

The production, marketing and research team of Taiyuan Iron and Steel Co., Ltd. jointly develops the product with relevant production enterprises, carries out a unique design around the needs of users, and strictly implements the fine quality control of the whole process. At present, the coefficient of linear expansion, flatness, same plate difference, surface quality and surface roughness of this kind of products of Taiyuan Iron and Steel Co., Ltd. all meet the stringent requirements of users, and successfully move from the laboratory to the market to achieve batch and stable supply.

In the future, TISCO will continue to carry forward the spirit of craftsmen, courageously be the vanguard of innovation and development, take the development of national "neck" key basic materials as its own responsibility, and never forget the initial intention of "industry to serve the country". In the R & D and manufacture of core materials, we will continue to show the hard core strength of TISCO.
