The first roll of 1180 MPa cold-rolled galvanized sheet rolled off the production line of LY Steel

Recently, the first roll of 1180 MPa galvanized product of LY Steel was successfully rolled off its cold-rolled No. 3 galvanized production line. Its excellent strength, corrosion resistance and green environmental protection characteristics will provide more competitive material solutions for new energy vehicles, high-end equipment manufacturing and other fields.
Nowadays, lightweighting has become the core development direction of materials in the fields of automobiles, rail transit, etc. Relying on technological upgrades, LY Steel continues to increase its efforts in product research and development. In the process of developing DP1180 galvanized steel sheets, it carefully designs and strictly controls each production link, and solves a series of process and technical problems. DP1180 galvanized steel sheets not only have high strength and good formability, but also meet the processing needs of complex parts. Through innovative alloy composition design and galvanizing process optimization, its corrosion resistance has been greatly improved, and the salt spray test life is extended by more than 50% compared with traditional high-strength steel, which can effectively extend the service life of terminal products.
After this product is used in the automotive field, it can reduce the weight of the car body by 15% to 20%, which can significantly reduce energy consumption and carbon emissions. At the same time, its excellent welding performance and surface quality will provide reliable material selection for key components such as new energy vehicle battery pack structural parts and body safety parts. This product can also be widely used in high-end home appliances, smart warehousing, engineering machinery, and other fields.
