GNEE Steel Hot Formed Automotive Steel
Cr-440-780-Dp-S is a type of automotive steel that is highly valued in the industry for its exceptional quality and durability. This cold rolled sheet has been specifically designed to meet the demanding requirements of modern-day automobiles, making it an ideal choice for manufacturers looking to produce vehicles with superior performance and safety features. Its unique composition, which includes chromium (Cr) and high-strength low-alloy (HSLA) steel, allows it to resist corrosion while also providing excellent strength and toughness. The "Dp" in its name stands for dual-phase, indicating that it has undergone a special manufacturing process that enhances its strength even further. With a tensile strength of 780 megapascals (MPa), this steel is capable of withstanding extreme conditions without compromising on quality or reliability. TM-2011-Cr-440-780-Dp-S Automotive Steel truly represents the pinnacle of automotive engineering excellence, ensuring that vehicle owners can enjoy unparalleled levels of safety and performance on the road.

Our Automotive Cold Rolled Steel Advantage
Extensive use
Cold-rolled steel plate with smooth surface and excellent processing, used for home appliances such as automobiles, refrigerators, washing machines, industrial equipment, and various building materials. With the development of the economy, cold-rolled steel sheets have been called necessary materials in modern society. Classification of cold-rolled products: hot-rolled pickling, hard-rolled coil, ordinary cold-rolled, galvanized (electro-galvanized, anti-fingerprint, hot-dip galvanized), galvanized, electro-tinned, color-coated, electrical steel (silicon steel sheet) wait.
Provide deep processing
The company's slitting machine, slitting line, cuts cold rolled steel coils into strips of various widths as needed, and then folds the strips into small coils for use in the next process. It is a necessary equipment for precision cutting of transformers, motor industries, and other metal strips. It is mainly used for strip cutting of materials such as tinplate, galvanized iron, silicon steel sheet, cold rolled strip, stainless steel strip, aluminum strip, steel strip, and other coils.
