Ultra-Wide Cold-Rolled Steel Redefines Vehicle Body Manufacturing
A state-owned steel manufacturer has pioneered 2150mm ultra-wide automotive steel with 0.02mm thickness precision using AI-driven rolling systems
. This innovation enables automakers to:
- Cut welding costs by 30%: Single-sheet roof panels replace multi-part assemblies (previously requiring 2+ welded sheets)
- Boost production efficiency: Smart control models reduce rolling time from 20 to 5 minutes per batch
- Achieve sustainability goals: 30% lower energy consumption compared to traditional lines, validated by IoT-powered resource optimization
Dual-Phase Steel Series Drives EV Lightweighting
The newly commercialized 590-1180 MPa dual-phase steel combines AI-optimized alloy design with advanced coating technology:
- 12% material cost reduction: Vanadium-titanium microalloying replaces rare metals, leveraging regional resource advantages
- 18% weight savings: Critical for battery enclosures and crash-resistant beams in electric vehicles
- Guaranteed 30-day delivery: Supported by ISO-certified production hubs serving 30+ global automotive plants
Market validation: fatigue life exceeds 1 million cycles (IATF 16949 certified), with applications confirmed by tier-1 suppliers.
