As the first titanium material project deployed by Hongwang Holding Group, Yangjiang Hongwang entered the titanium material sector in the second half of last year. Leveraging the company’s foundation in the stainless steel cold rolling field, the project has introduced automated equipment such as 20-high rolling mills, degreasing and cleaning machines, annealing furnaces, and tension leveling machines, and officially started production this year.

Currently, China's R&D in solid-state transformers is progressing in sync with international efforts, representing a critical period to seize opportunities, vigorously develop the technology, and gain a competitive edge. On May 15th, experts from domestic research institutes, universities, leading enterprises, and industry associations gathered in Yancheng, Jiangsu Province.

Silicon steel is known as the "pearl" in the steel industry, renowned for its complex production process and high technological content. In recent years, China's silicon steel industry has achieved a leap from following to leading, with a production capacity of 18 million tons. The proportion of high-grade products has significantly increased, and the export volume has reached a historical high.

316L stainless steel is an ultra-low carbon pure austenitic stainless steel with excellent weldability and low susceptibility to intergranular corrosion. However, due to its low thermal conductivity and high linear expansion coefficient, the welded joints of this steel type may experience significant tensile stress during the cooling process. When the welding heat input is high and the cooling rate is slow, it is prone to forming hot cracks, corrosion cracks, and deformations.

With key control precision reaching the micron level, the production capacity of this line is approximately three times higher than that of foreign heat-resistant notching production lines, enabling large-scale production.

Driven by the dual factors of demand upgrading and intensified competition, the technological development direction of non-oriented silicon steel has become very clear: thin gauge, low iron loss, and high strength. These three characteristics directly determine the market competitiveness of the product.

Not long ago, the BYD Yangwang U9 engineering test vehicle set a new global record for the highest speed of an electric vehicle, reaching 472.41 km/h at the German ATP test field. The vehicle is equipped with the world's first high-performance motor capable of 30,000 rpm, which utilizes high-end electrical steel.

The core demand for silicon steel has always resonated with the development of downstream industries. At present, the demand for non oriented silicon steel is growing, driven by four major fields, among which emerging tracks such as new energy vehicles, humanoid robots, and low altitude economy have become the "main growth force" of high-grade non oriented silicon steel.
