Recently, Deqing Linyuan Metal Products Co., Ltd. (hereinafter referred to as "Linyuan Metal"), which has been deeply engaged in the metal wire drawing field for 18 years, announced that it has successfully broken through the core technology of special steel wires in collaboration with a university R&D team and officially launched 2000MPa grade ultra-high strength corrosion-resistant steel wire products. This product can bear a weight of 0.2 tons per square millimeter, and its corrosion resistance is more than four times higher than that of traditional products. This marks another breakthrough in China's independent capabilities in the medium and high-end metal wire drawing field, completely breaking the import dependence in some high-end application scenarios.
As a professional enterprise specializing in metal wire drawing production, Linyuan Metal, relying on the standardized control of the ISO9000 quality management system, has achieved dual innovations in material formulas and production processes after two years of technological breakthroughs. Through the optimization of the "trace element synergic strengthening" technology, the tensile strength of the product has exceeded 2000MPa, which is 7.5% higher than the international mainstream standard of 1860MPa. At the same time, it maintains an excellent elongation of ≥5%, which can meet the toughness requirements under complex working conditions such as strong wind and high humidity. The zinc-aluminum-magnesium alloy coating created by the innovative "post-plating cooling control" process makes the product's corrosion resistance far exceed that of traditional galvanized steel wire, and extends its service life to over 30 years.
It is understood that this type of ultra-high strength steel wire has passed the authoritative third-party testing and has been successfully applied to the prestressed components of a certain cross-sea bridge in China and the manufacturing of wind turbine tower bolts. With the rapid expansion of emerging fields such as new energy and rail transit, the market demand for high-strength and corrosion-resistant wire drawing materials has grown at an average annual rate of over 8%. The technical director of Linyuan Metal stated that the launch of this new product not only fills the gap in the company's high-end special steel wire field, but also precisely matches the core demands of major engineering construction and high-end equipment manufacturing. The product orders have covered multiple key projects in East China and North China.
Industry experts point out that in 2024, the output of China's wire drawing industry will reach 48.6 million tons, among which the proportion of high value-added alloy steel and stainless steel wire drawing has risen to 21.5%, and the trend of industrial structure transformation towards high-end is obvious. This technological breakthrough by Linyuan Metal not only conforms to the direction of industry upgrading but also provides a referenceable "industry-university-research-application" collaborative model for technological innovation in domestic metal wire drawing enterprises.
