Overview of Baosteel Automotive AHSS
BaoSteel has been working on R&D of high-end products. In recent years, to meet the demand of light-weighting of auto-body and environment protection, BaoSteel invested a lot in developing high strength steel, especially advanced high strength steels (AHSS) strengthened by phase transformation as shown in Fig.1. The product line of AHSS is listed below.

Commercialized AHSS products are listed in Table 1. The highest strength of cold rolled (CR) products is 1700MPa, for hot-dip galvanized (HDG) ones is 1180MPa, and for electrolytic galvanized (EG) ones is 980MPa.
Table1 The AHSS products in BaoSteel
Fig.2 Main applications of AHSS for auto body
AHSS is well suited for automotive structural and safety parts (Fig. 2), contributing to both the weight reduction of car body and the promotion of passive safety and increasing the cost benefit of automotive.
Note: In the table, even there are differences between BaoSteel products and some similar steels nominated by other standards or companies, they belong to the same grade, and the difference of tensile strength values should be less than 20 MPa. So, please refer to BaoSteel product category in the steel selection, for example, DP590 and DP600 are the same grade so refer DP590 for the product ability. TRIP 780 and TRIP 800 are the same too.

BaoSteel Automotive Advanced High Strength Steels 2
DP (Dual Phase) Steels
Microstructure:The microstructure of these steels is composed of ferrite and martensite. Martensite islands distribute dispersively in the ferrite matrix. Due to the soft ferrite matrix, DP steel exhibits good formability, while the hard martensite islands contribute to its high strength. Products with different yield ratio can be produced for different applications.
Properties: No Yield point; No room-temperature aging; Low Yield/Tensile Strength Ratio; High strain hardening exponent and high bake hardening value.
Applications: DP high strength steels are preferred to manufacture structural parts. It is widely applied to structural components, reinforcement and anti-collision components, such as underbody cross member, track, bumper, bumper reinforcement structure etc.

TRIP (Transformation Induced Plasticity) Steels
Microstructure: The microstructure of these steels is composed of ferrite, bainite and retained austenite with a volumefractionof7~15%.(Fig.7)
Properties: These steels have good formability due to the transformation of retained austenite into martensite during plastic deformation (transformation induced plasticity effect). TRIP steels exhibit good combination of high strength and high ductility. Moreover, TRIP steels show high energy absorption and high strain hardening capacity.
Application: Structural and reinforcement parts of complex shape, such as B-pillar reinforcement panels.

Microstructure: Almost full martensite. (Fig.9) Properties: High Yield/Tensile Strength Ratio; High tensile strength; Relatively low elongation; Delayed fracture should be considered.
Applications: MS steels are suited for simple cold stamped parts and roll formed parts with a relatively single interface, such as bumper, threshold reinforcing plate and the side door anti-collision rod.
BaoSteel Automotive Advanced High Strength Steels 6
CP (Complex Phase) Steels
Microstructure: Ferrite/bainite matrix with small amounts of martensite, retained austenite and pearlite. (Fig.11)
Properties: An extreme grain refinement is created by retarded recrystallization or precipitation of micro-alloying elements like Ti or Cr. In comparison with DP steels, CP steels show significantly higher yield strength, bendability and hole expansion ratio at the same strength level. CP steels are characterized with high energy absorption and goodstretchflangingformability.
Applications: Suspension parts, B-pillar, bumpers, seat slide.

Q&P (Quenching and Partitioning) Steels
Microstructure: The microstructure is composed of ferrite, bainite and retained austenite with a volume fraction of 5~10%.(Fig.13)
Properties: Benefiting from the TRIP effect of retained austenite, Q&P steels exhibit quite high strain hardening capacity, and higher ductility and formability than other UHSS with same strength level.
Applications: Q&P steels are suited for the automotive structural and safety parts with complex shapes.

TWIP (Twinning Induced Plasticity) Steels
Microstructure: Full austenite (Fig.17) Properties: TWIP steels are full austenitic steels with high C, Mn and Al. TWIP steels have very high strain hardening capacity due to dynamic refinement effect caused by the continuous activation of twining during cold deformation. TWIP steels developed by BaoSteel exhibit an elongation of over 50% with the tensile strength of 1000MPa.
Applications: TWIP steels have very good formability and ultra-high strength, which are suited for manufacturing structural and safety parts with very complex shapes.
