Types of high-strength steel for automobiles:
1. Dual Phase Steels
2. Complex Phase Steels (CP Steel)
3. Transformation Induced Plasticity Steels (TRIP steels)
4. Martensitic Steel
5. Quenching and Partitioning Steels (QP steel)
6. Twining Induced Plasticity Steels
7. Boric steel (PH steel or B steel, Press Hardening/Boron Steel)
1. Performance characteristics of dual phase steel (DP steel): no yield elongation, no room temperature aging, low yield strength ratio, high work hardening index, and high bake hardening value.
Typical application: DP series high-strength steel is currently the preferred steel type for structural components, widely used in structural components, reinforcement components, and anti-collision components. For example, cross components under the car, rails, crash bars, and reinforced structural components of crash bars.
2. Performance characteristics of duplex steel (CP steel): fine grain size and high tensile strength. Compared with dual phase steel with the same level of tensile strength, its yield strength is significantly higher. It has good bending performance, high hole expansion performance, high energy absorption capacity, and excellent flanging forming performance.
Typical applications: chassis suspension components, B-pillars, bumpers, seat rails, etc.
3. Performance characteristics of phase transformation induced plasticity steel (TRIP steel):
The organization contains residual austenite and has good formability. During the forming process, residual austenite gradually transforms into hard martensite, which is beneficial for uniform deformation.
TRIP steel also has the characteristics of high collision absorption energy, high strength plasticity product, and high n-value.
Typical application: Components with relatively complex structures, such as B-pillar reinforcement plates, front longitudinal beams, etc.
4. Performance characteristics of martensitic steel (MS steel):
High yield to strength ratio, high tensile strength, and relatively low elongation, attention should be paid to the tendency of delayed cracking.
It has the characteristics of high collision absorption energy, high strength plastic product, and high n-value.
Typical applications: Cold stamping of simple parts and rolling formed parts with relatively single cross-sections, such as bumpers, door sill reinforcement plates, and side door interiors
