Explore our high-performance formable steel products designed to meet rigid international structural and forming requirements.
In modern precision manufacturing, selecting high-performance raw materials is critical to achieving component integrity. Cold rolled (CR) steel coils, particularly formable and deep-drawing grades, are highly valued for their dimensional accuracy, outstanding surface finish, and excellent mechanical properties. These coils serve as the backbone of downstream manufacturing industries, where materials must withstand severe plastic deformation without fracturing or suffering from localized thinning.
At the core of deep-drawing formable CR steel is Interstitial-Free (IF) technology. By reducing interstitial elements like carbon and nitrogen to ultra-low levels (typically C ≤ 0.005%, N ≤ 0.004%) and adding stabilizing micro-alloys such as Titanium (Ti) and Niobium (Nb), we bind the remaining interstitials. This removes dynamic strain aging, allowing the steel to maintain excellent ductility and preventing the formation of stretcher strains (Lüders lines) during stamping.
To transform rigid cold-reduced iron grain bands into highly plastic equiaxed grains, the cold rolled coils must undergo thermal treatment. Whether utilizing continuous annealing lines (CAL) or batch annealing furnaces (BAF), the grain recrystallization is carefully monitored. Annealing parameters are precisely calibrated to maximize the Lankford coefficient (mean plastic strain ratio, r-value) and the strain-hardening exponent (n-value). A higher r-value (typically between 1.6 and 2.2 for SPCE/DC04 to SPCG/DC06 grades) ensures exceptional resistance to thinning, making deep cup drawing possible.
Furthermore, modern applications demand strict control over the surface roughness (Ra). Formable CR steel coils are finished via a dedicated skin-pass (temper rolling) mill. This final process imprints a controlled roughness on the steel surface, providing two major benefits: it acts as a micro-reservoir for stamping lubricants, reducing frictional wear, and it ensures an optimized texture for subsequent painting or galvanizing processes.
The manufacturing sector is changing rapidly. As global industries push toward lightweight and carbon-neutral solutions, the technical roadmap for cold rolled steel focuses on developing Next-Generation Advanced High-Strength Steels (AHSS) and Ultra-High-Strength Steels (UHSS) with enhanced formability.
Developing Dual-Phase (DP) and Transformation-Induced Plasticity (TRIP) steels that combine high tensile strength (above 590-980 MPa) with sufficient elongation for complex geometric forming, optimizing safety in structural applications.
Reducing carbon emissions during production by transitioning toward hydrogen-reduced ironmaking, clean energy continuous annealing, and recycling steel scraps to lower the overall lifecycle carbon footprint.
Integrating AI-driven visual inspection and automated gauge control systems (AGC) to achieve thickness tolerances within ±0.01 mm, drastically reducing material waste for automated end-user production.
High-formability cold rolled steel is essential for multiple industries, providing stability, structural integrity, and manufacturing efficiency.
Automotive components require high structural strength and lightweight characteristics. Our deep-drawing CR coils (such as SPCF, SPCG, DC05, and DC06) are used for manufacturing intricate components like car doors, roofs, floor panels, and engine hoods. Their consistent mechanical properties guarantee clean stamping cycles, reducing springback issues and scrap rates.
For white goods (refrigerators, washing machines, microwaves), surface finish and precise corners are essential. Our CR coils feature excellent surface flatness, making them ideal for high-definition coating, embossing, and bending. This ensures panels remain free of visible defects and retain their shape over time.
In construction, cold-formed sections, light steel framing, HVAC ducting, and cable trays rely on cold rolled steel for dimensional precision. When combined with protective zinc coatings, these components provide reliable structural support in commercial and residential construction project sites globally.
Strategically located in Tangshan City, Hebei Province—the historic epicenter of China's iron and steel manufacturing—Hansheng Technology (Hebei) Co., Ltd. has grown into a major exporter of premium steel products since our establishment in 2006.
Our manufacturing facility operates 8 high-capacity production lines with a total annual output of 650,000 metric tons. Located just 150 kilometers from both Beijing and the major logistics hub of Tianjin Seaport, we offer fast domestic and international distribution. This geographic advantage minimizes inland transport time and exposure to moisture, reducing the risk of transit oxidation for our cold rolled shipments.
Under our Core Philosophy of "honoring contracts and keeping promises," we treat all our clients as long-term partners. Our integrated quality management systems ensure that from the raw slab sourcing phase to final packing, every cold rolled coil meets strict international specifications.
International steel procurement involves managing quality risks, shipping lead times, and complex regulatory standards. To support global procurement agents and engineers, we structure our production processes around three core pillars:
We supply products according to major global standards including ASTM A1008 (Grade 1008, CS Type A/B/C, DS Type A/B), JIS G3141 (SPCC, SPCD, SPCE, SPCF, SPCG), EN 10130 (DC01, DC03, DC04, DC05, DC06), and GB/T 5213.
Certified under ISO 9001:2000 and ISO 14001, we conduct pre-shipment inspections for every batch. These evaluations include chemical analysis, tensile testing, cup drawing testing, and roughness verification.
To prevent rust during long ocean transits, we use multi-layer packaging: heavy-duty VCI (Volatile Corrosion Inhibitor) anti-rust paper wrapping, metal edge guards, inner and outer steel protective bands, and robust wooden runners for stability.
