Recently, the high-strength, high-bend, high-corrosion-resistant steel DP1310GA independently developed by Baowu Central Research Institute achieved its world premiere at Zhanjiang Iron and Steel. This product is the first in the world to achieve a breakthrough in 1300MPa strength level hot-dip galvanized ultra-high-strength steel, high bending, and high corrosion resistance. At the same time, it fills the gap in ultra-high-strength steel for automobiles that has both high strength, high bending, and high corrosion resistance. Baowu provides Baowu solutions to meet the differentiated demand for parts in the automotive industry.
In recent years, with the high-end development of the automobile industry, the requirements for the strength, bending performance, and corrosion resistance of automobile steel have become increasingly higher, especially for the safety, safety, and corrosion resistance of key components such as automobile bumpers, anti-collision beams, and battery packs. Formability and corrosion resistance requirements are also more stringent. At present, hot-dip galvanized ultra-high-strength steel for automobiles at home and abroad is mainly concentrated in the 780-1180MPa strength level. Hot-dip galvanized ultra-high-strength steel with high bending and high corrosion resistance of 1300MPa strength level and above is in a blank state and cannot meet the increasing demand for high-end automobiles. Steel demand.
In order to fill the gap in hot-dip galvanized ultra-high-strength steel with high bending and high corrosion resistance, Baowu Central Research Institute broke through the problems of high-performance alloy composition design, consistent manufacturing process control, ultra-high-strength steel plateability and GA coating alloying process control, and successfully Developed high bending and high corrosion resistance DP1310GA with completely independent intellectual property rights. This product has overcome a series of technical barriers, with a tensile strength of more than 1,300MPa. It has greatly improved the safety, formability and corrosion resistance of automotive materials in terms of bending performance and corrosion resistance. At the same time, this product fills the product gap at home and abroad, providing automobile OEMs and parts manufacturers with more abundant products for key components such as bumpers, anti-collision beams, and battery packs that require high corrosion resistance and safety. Material selection plan to meet the automotive industry’s lightweight and low-carbon needs for new materials.
In the next step, Baowu will further develop hot-dip galvanized ultra-high-strength steel for automobiles with higher strength, high bending and high corrosion resistance based on the successful development of high-bending and high-corrosion-resistant steel DP1310GA to provide more low-carbon and environmentally friendly products. , high-quality new materials contribute to Baowu’s strength.
