DC06 Steel Coil

DC06 Steel Coil features extremely high surface precision, suitable for high-end appearance processing. Its surface grade is FC (fine surface), and a higher precision surface can be customized as required. The surface roughness Ra is ≤0.4–1.0 μm, with no scale, no scratches, no pitting and no slip lines. The thickness tolerance is ±0.015 mm, ensuring batch uniformity without thickness difference, and the plate shape wave height is ≤5I. The phosphating film has excellent adhesion, which is suitable for high-end electrostatic spraying, powder spraying, electroplating, aluminum-zinc coating/galvanizing processes. The coating is not easy to fall off or bubble, making it suitable for products with extremely high appearance requirements such as automotive outer panels and high-end home appliance exposed parts.

DC06 Steel Coil has a complete range of specifications, supporting flexible delivery of spot goods and customization. The thickness ranges from 0.3–2.5 mm, with mainstream specifications of 0.5/0.6/0.8/1.0 mm; the width ranges from 800–1800 mm, which can be slit to 20mm, and slitting, leveling and shearing are supported. The surface treatment options include bright surface, oiled, film coated and chrome-free passivation. The delivery state is soft state (annealed), which can be directly deep drawn after unpacking without additional softening treatment. It is suitable for batch and small-batch high-end orders from automobile factories, high-end home appliance factories and precision drawing parts factories. Regular specifications can be delivered in 1–3 days, and customized specifications can be delivered in 7–12 days, supporting JIT delivery.

DC06 Steel Coil has complete qualifications, traceability and is suitable for high-end export orders. It implements the standards of EN 10130 and GB/T 5213, complying with the ISO3574 international standard. The material certificates include MTC original factory report, and the mechanical properties and chemical composition are traceable. It supports automobile enterprise standards such as VW238-100 and GMW14872, and has passed the EU CE and US FDA compliance certifications. It is suitable for automotive outer panels, high-end home appliances, precision electronics, medical devices and high-end export markets in Europe and the United States.

FAQ

Q1: What are the differences between DC06 and DC05? Why is DC06 the preferred choice for extreme deep drawing?
A: The core difference lies in forming limits, stability, and surface finish. DC05 has an elongation ≥38% and an r-value ≥1.6, suitable for high-difficulty deep drawing, but there is still a risk of cracking in ultra-thin parts and sharp-edged structures. DC06 (top-grade IF steel) has an elongation ≥40% and an r-value ≥2.0, no aging characteristics, an extreme drawing ratio ≥2.5, and can form double-curvature sharp-edged structures in one piece without cracking or wrinkling, and has no slip lines marks on the surface. Conclusion: For high-end appearance parts, extreme deep drawing components, and stable mass production, DC06 is the preferred choice, offering lower long-term total costs.

Q2: Can DC06 be directly used to make food-grade kitchenware (such as cake molds and baking pans)?
A: Yes, but it requires food-grade surface treatment. DC06 is an ultra-low carbon clean steel with extremely low impurities and fine grain size. When used for food contact parts, it requires food-grade electroplating, non-stick coating, or electrolytic polishing. We can provide material test reports and heavy metal migration compliance certificates, suitable for export food contact kitchenware orders and compliant with FDA requirements.

Q3: Can DC06 surface be directly sprayed/electroplated/coated with aluminum-zinc?
A: Absolutely, and the adhesion is superior to DC05 and ordinary cold-rolled steel. The FC-grade surface has uniform roughness, free of oxide scale and oil stains, suitable for electrostatic spraying, powder coating, nickel-chromium electroplating, hot-dip galvanizing, aluminum-zinc coating, etc. The coating resists peeling and blistering, especially suitable for automotive exterior panels, high-end household appliance exposed parts, and other products with extremely high appearance requirements.

Q4: Do you have regular specifications in stock? What is the lead time? Can ultra-thin and ultra-wide specifications be customized?
A: Standard sizes (0.5/0.6/0.8/1.0 mm × 1000/1250/1500 mm) are readily available, with delivery in 1-3 days. Same-day slitting/leveling is possible. Ultra-thin (0.3mm), ultra-wide (1800mm), and custom thicknesses and widths are available, with delivery in 7-12 days. JIT delivery is available for bulk purchases, ensuring seamless integration with production lines.

Q5: What should I pay attention to when purchasing DC06? How can I avoid cracking during extreme deep drawing?
A: Three key points: 1. Purchase genuine top-grade IF steel DC06, verifying C≤0.006% and elongation≥40%, avoiding mislabeled DC05 material passed off as DC06; 2. Increase the die corner radius, optimize blank holder force, and ensure adequate lubrication (recommended ester-based oil film thickness ≥3.5μm) to suit the forming characteristics of DC06; 3. Choose soft-annealed raw materials, rejecting work-hardened material and remelted scrap-based stock. We offer free stamping trial samples and process guidance to help reduce scrap rates.
