Baosteel has been committed to the research and production of high-end automotive sheets. In recent years, combined with the requirements of lightweight vehicle bodies and green environmental protection, it has vigorously developed various types of high-strength automotive steel sheets, especially advanced high-strength steel sheets based on phase change strengthening, which mainly include:
1. Duplex steel
2. Phase transformation induced plastic steel
3. Complex phase steel
4.Martensitic steel
5. Quenched ductile steel
6. Boron steel

Advanced high-strength steel is mainly used in structural parts and safety parts of automobile body-in-white. Optimizing the use of advanced high-strength steel can reduce the weight of the car body, improve the passive safety of the car body, and improve the cost-effectiveness of the vehicle.

The available varieties of Baosteel’s advanced high-strength steel include: the highest strength of plain cold steel reaches 1700MPa, and the highest strength of electro-galvanized steel reaches 780MPa.
