DC04EK/DC06EK Enamel Steel Base Overview

DC04EK, DC06EK areEN10209 Standard for Cold-Rolled Steel Specialized for EnamelBaosteel's high-end EK series enamel cold-rolled coils, produced under the Q/BQB461-2023 enterprise standard, are the mainstream deep-drawing enamel substrates for kitchen and bathroom appliances and sanitary ware. Unlike standard BTC1 enamel steel, the EK series is specifically optimized for enamel processes: ultra-low carbon content and exceptional purity eliminate defects such as fish-scale cracking, pinholes, bubbles, and enamel chipping after high-temperature firing, while delivering excellent stretch-forming performance.

Two distinct material gradients, precisely tailored to different process requirements:DC04EK is standard deep-draw enamel steelSuitable for standard deep-drawn and moderately complex enamel workpieces; cost-effective.DC06EK is a premium ultra-deep-drawing enamel steel.Superior elongation, toughness, and forming stability. Designed specifically for multi-pass complex drawing, ultra-thin irregular shapes, and high-difficulty enamel forming parts—the preferred raw material for premium enamel manufacturing. Both materials are compatible with mainstream enameling processes, including wet enameling, electrostatic dry powder enameling, one-coat-one-fire, and two-coat-one-fire.

1. Definition and Grade Classification of DC04EK/DC06EK

The EK series is cold-rolled steel specifically engineered for enameling. The "EK" suffix denotes a material optimized for the enameling process, distinguishing it from standard ED series and general-purpose DC series cold-rolled sheets. Key grade specifications and classifications are detailed below:

• Execution Standard: EN10209:2013 European Standard, Baosteel Q/BQB461-2023 Enamel Steel Standard

• DC04EK location: Standard deep-drawing enamel grade, elongation ≥ 36%, suitable for conventional deep drawing, curved shapes, and box-type enamel workpieces

• DC06EK locationSuper Deep-Drawing Enamel Grade: Elongation ≥ 38%, IF interstitial-free steel, engineered for extreme deep drawing of ultra-thin and complex-shaped enamel components.

• Sort by Level: DC01EK < DC04EK < DC06EK, with performance increasing at each level; no backward replacement is allowed.

• Process Compatibility: All models resist fish-scale cracking and high-temperature thermal shock; both double-sided and single-sided enamel processes are fully compatible.

II. DC04EK/DC06EK Core Performance Advantages

DC04EK and DC06EK enameled steel is produced using ultra-low carbon refining and precise annealing, delivering superior formability and enamel compatibility to resolve key industry pain points:

• Superior enamel defect resistanceExtremely low impurity levels and uniform microstructure in steel. After enamel firing, no pinholes, bubbles, fish-scale cracking, or delamination occur. The enamel layer is dense and uniform, significantly improving the yield rate of finished enamel products and supporting long-term mass production.

• High-grade deep-drawing capabilityDC04EK meets standard deep drawing requirements; DC06EK offers ultra-high elongation and low springback, enabling multi-pass continuous drawing of complex curved surfaces and thin-walled parts without cracking, thinning, or wrinkling, with exceptional forming accuracy.

• High-temperature resistant and thermally shock stableWithstands high-temperature firing at 820–860°C. Maintains shape and strength through repeated firing cycles, with excellent thermal expansion compatibility. Ensures a robust bond between the porcelain layer and substrate, preventing leaks or delamination during long-term use.

• Dual-process universal compatibilitySupports both traditional wet glazing and advanced electrostatic dry enamel processes. Stable production for single-sided and double-sided enameling, compatible with all new and existing enamel lines.

• Premium, stable board qualityFlat, smooth surface with no oxidation or scratches; uniform roughness and high substrate consistency. Batch production ensures no color variation or process defects.

Storage Usage ReminderBoth DC04EK and DC06EK are bare cold-rolled enamel substrates without anti-rust plating. They oxidize and rust easily, requiring sealed dry storage and continuous oil protection throughout the process. During processing, avoid surface scratches and oil residue to prevent compromising enamel adhesion and firing results.

Q1: What is the difference between DC04EK, DC06EK, and standard BTC1 enamel steel?

BTC1 is a universal enamel steel for home appliances. The EK series uses an EU-standard optimized enamel material with superior fish-scale burst resistance and higher forming grades. DC04EK/DC06EK supports complex deep drawing and multiple enamel firing cycles, offering better process stability than standard BTC1—ideal for mid-to-high-end enamel products.

Q2: Can DC04EK and DC06EK be used interchangeably?

DC06EK can fully replace DC04EK, yielding better forming and enamel results. DC04EK cannot replace DC06EK; using DC04EK for complex deep-drawn parts may lead to cracking or poor forming.

Q3: Can the Enamel Steel EK series be used for both wet and dry enameling?

Yes. DC04EK and DC06EK are fully compatible with wet glazing and electrostatic dry enamel processes, supporting mainstream methods such as one-coat-one-fire and two-coat-one-fire, with exceptional process compatibility.

Q4: Is DC06EK the best cold-rolled substrate for premium enamel?

In the civilian industrial enamel sector, DC06EK ultra-deep-drawing enamel steel offers top-tier formability and resistance to firing defects. It is the preferred substrate for high-end bathtubs, kitchen appliances, and precision enamel components, with exceptional mass production stability.
