Compared with ordinary high-strength steel cold-rolled products, DP series high-strength steel cold-rolled automotive sheet products have better composition control, more stable mechanical properties, and better formability.
DP series high-strength steel cold-rolled automotive sheet products have a lower yield to strength ratio, resulting in less rebound after cold forming, which can more accurately control the dimensional accuracy of the parts. Due to the use of advanced cooling technology in actual production, Baosteel's DP series high-strength steel for automotive panels is obtained through rapid cooling of low-carbon and low alloy components, which have good weldability and can be applied to various traditional welding methods.

Definition: Baosteel Group will provide a tensile strength of over 1000MPa (megapascals)
The ultra high strength steel used for automobile lightweighting is named Jipa steel ® (X-GPa) ®).
Baosteel has been committed to the research and production of high-end automotive panels, and in recent years
Combining the requirements of lightweight vehicle body and green environmental protection, vigorously developing Jeep steel ®
(X-GPa) ®) Product. Jipa steel ® Mainly used for car body frames,
It can significantly improve the active safety of automobiles while achieving lightweight and weight reduction
Effect. It is a green product implemented by Baosteel Group on the path of sustainable development
Exemplary. BaoQP ® Quenching and Partitioning Steel
QE Steel with High Hole Expansion
DP Dual Phase Steel
DH High Plasticity Dual Phase Steel
CP Composite Phase Steel
CH High Plasticity Composite Steel
MS Martensite Steel
TWIP Twining Induced Plasticity Steel
PHS hot forming steel/Press Hardening Steel, performance characteristics: QP steel uses martensite as the matrix phase and utilizes residual austenite
The TRIP effect of the body during deformation can achieve high machining hardness
Due to its chemical ability, it has higher plasticity and
Forming performance. Adopting Baosteel's innovative low point welding LME product design standards
And the manufacturing process makes QP steel galvanized products have low LME sensitivity
It effectively improves the spot welding performance of materials.
Main uses
Components. 980MPa grade QP steel is Baosteel's first global first product. order
Former BaoQP ® A large number of commercial applications have been achieved nationwide,
Mainly used for A-pillar reinforcement plate, B-pillar reinforcement plate, and door hinge reinforcement
Parts such as boards. Performance characteristics: With no yield extension, no room temperature aging, and low yield strength
The characteristics of high ratio, high work hardening index, and high baking hardening value.
Liang corrosion-resistant series products: using a high corrosion-resistant combination independently developed by Baosteel
Process can effectively remove surface alloying element enrichment and optimize the surface
Quality, improve the corrosion resistance of ordinary cold products, and enhance the electrophoretic coating performance
By doing so, we can obtain a high surface quality common cold DP product family.
High corrosion resistance, good coating, and advanced surface DP cold products can expand applications
Used for components in the vehicle body that require high corrosion resistance, such as:
Safety components such as door sills, seat crossbeams, door crash beams, A-pillars, B-pillars, etc
Application of structural components, especially in parts such as unpainted seat frames
The prospects are great.
Main use: DP steel series is currently the preferred steel for structural parts
Among them, products with low yield to strength ratios are mainly used for A-pillar reinforcement plates and B
Parts such as column reinforcement plates, with high yield to strength ratios, are mainly used in the transverse direction of the car bottom
Beam, threshold, door collision beam, seat frame, battery pack frame, etc
