Extra Ultra Deep Drawing Quality · Anti-Fishscale Guaranteed · Ideal for Traditional Enameling Process Complex Stamped Enamelware, Water Heater Tanks, Automotive Components, High-End Sanitary Ware
📋 Product Overview
DC06EK is a premium cold rolled low carbon steel sheet specially designed for vitreous enamelling, conforming to GB/T 13790-2025. With stamping level 06 (extra ultra deep drawing) and EK classification (traditional enameling process), it offers excellent extra ultra deep drawability, superior enamel adhesion, and reliable anti-fishscale performance. Titanium-stabilized grade ensures superior formability. Supplied in annealed + skin-passed condition, mechanical properties are guaranteed for 6 months from manufacture date.
📌 Grade code: D (cold forming) + C (cold rolled) + 06 (stamping level 06) + EK (traditional enameling).

📌 Key Features Ultra-low carbon (≤0.008%) and titanium stabilization ensure excellent extra ultra deep drawability and superior weldability; aluminum content (≥0.010%) promotes enamel adhesion and prevents fishscale. Strict P (≤0.020%) control for outstanding enameling performance. Ti addition fixes C and N for superior aging resistance.

📌 EK Classification: Suitable for traditional two-coat enameling process. Titanium-stabilized ultra-low carbon content ensures superior formability for complex shapes while maintaining excellent enamel wettability and anti-fishscale performance. No stretcher strain marks guaranteed during use per GB/T 13790-2025 Table 7.
❓ Frequently Asked Questions
📦 What is the lead time for DC06EK enameling steel?
Our standard lead time is 35-55 days after order confirmation, depending on quantity and specification requirements. Express delivery options are available upon request.
💰 What is the minimum order quantity (MOQ)?
The typical MOQ is 25 tons per specification. Trial orders of 10-15 tons can be arranged for customer qualification. Contact us for sample requests.
🧪 How does DC06EK prevent fishscaling during enameling?
DC06EK features strictly controlled chemistry (ultra-low carbon ≤0.008%, titanium stabilized, aluminum killed) and hydrogen permeation test value TH ≥ 6.7 min/mm² per GB/T 13790-2025 Annex B, which effectively blocks hydrogen diffusion and prevents fishscale defects. We can provide the hydrogen permeation test report upon request.
🎨 What surface quality levels are available for DC06EK?
We offer FB (finish B), FC (finish C), and FD (superior) surface quality per GB/T 13790-2025 Table 8. FC and FD surfaces are guaranteed to have no visible defects on the better side, ensuring excellent enameling appearance.
📄 How long are the mechanical properties guaranteed?
Per GB/T 13790-2025 clause 7.2, mechanical properties (yield strength, tensile strength, elongation) are guaranteed for 6 months from the date of manufacture, provided proper storage conditions. However, due to aging effects, we recommend using the material as soon as possible for optimal forming performance.
🚢 What packaging options are available for export?
We offer export-grade moisture-proof packaging including VCI anti-rust paper, waterproof underlayer, edge protection, and seaworthy wooden pallets. Standard oiled or dry (non-oiled) options are available based on your requirements.
