Introduction
Baosteel Cold Rolling high strength steel plate and strip (hereinafter referred to as cold rolled plate and strip) is the vision of Baosteel Group Co., Ltd. to meet the novel development requirements of the current automotive industry, optimize the microstructure of steel, improve the mechanical properties and processed performance of cold rolled plate and strip to meet the needs of automotive lightweight. It is a kind of automobile steel for multi-functional structural parts.
Application
Baosteel Cold Rolling high strength steel plates/strips are widely used in anti-rolling, anti-impact and anti-fatigue automotive parts, such as the side modules, beams, bulkheads, cowl plates, floors and fenders of the body structure. Moreover, the product quality has reached the leading domestic level.
Features
Baosteel Cold Rolling high strength steel plate and strip adopt phosphorus-alloying technology. After heat treatment and cold rolling, the tensile strength of the product reaches 1200MPa (1225MPa or above). The product has high strength and decarburization, improved impact energy absorption and fatigue strength, low temperature-resistant formability, improved weldability and easy to manufacture stampings.
Advantage
Adopting phosphorus alloying technology can significantly improve the strength and elasticity coefficient of cold rolling steel, improve the impact energy absorption and fatigue strength, and improve the low temperature-resistant formability and stamping processability. Therefore, Baosteel Cold Rolling high strength steel plate/strip has the following advantages compared with traditional steel.
1. High strength. The product can reach the tensile strength of 1200MPa (1225MPa or higher).
2. Better formability. The product can maintain good formability despite its high strength.
3. Excellent weldability. The product has excellent welding performance, which can reduce the amount of welding processes and welding time, improve the quality of welding and reduce the production cost.
4. Easy stamping. The product has good stamping performance, which can reduce the stamping cost while maintaining the initial quality.
Conclusion
In summary, Baosteel Cold Rolling high strength steel plate and strip has many advantages, including high strength, better formability, excellent weldability, easy stamping and more. It has been widely used in automobiles, and its performance has reached the domestic leading level.
