Cold-rolled automotive steel is an essential material for manufacturing high-quality car parts. Known for its strength, durability, and smooth finish, it is widely used in creating car body panels, chassis, and other structural components. At Promisteel, we take pride in offering premium-grade cold-rolled steel designed specifically for the automotive industry.
| Grade | Thickness (mm) | Width (mm) | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|---|---|
| SPCC | 0.3 - 2.0 | 600 - 1500 | 270 - 410 | 210 - 250 | ≥28 |
| ST12 | 0.3 - 4.0 | 600 - 1500 | 270 - 410 | 250 - 300 | ≥30 |
| DP600 | 0.8 - 3.0 | 600 - 1500 | 550 - 600 | 420 - 480 | ≥15 |
| TRIP700 | 0.6 - 3.0 | 600 - 1500 | 700 - 750 | 550 - 600 | ≥15 |
SPCC and ST12: Known for high elongation and formability, ideal for lightweight auto parts.
DP600: Offers a great balance of strength and flexibility for structural and safety-critical components.
TRIP700: Exceptional tensile strength for impact-resistant and high-safety applications.
These grades provide superior performance for sheet metal car bodies, chassis frames, and automotive structural parts, ensuring safety, durability, and efficiency.
High Strength and Durability
Cold-rolled steel offers exceptional tensile strength, ensuring durability even under constant mechanical stress in automotive parts.
Superior Surface Finish
The cold rolling process creates a smooth, defect-free finish, making it perfect for aesthetic applications like outer panels and vehicle interiors.
Excellent Formability
Easily shaped into complex designs, cold-rolled steel is ideal for intricate automotive components like dashboards and interior frames.
Corrosion Resistance
Engineered for resilience, it withstands harsh environmental conditions, maintaining strength and reducing rust risks over time.
Tailored Properties
Promisteel customizes cold-rolled steel to specific thicknesses, mechanical properties, and coatings to meet diverse automotive requirements.
