DC04 Cold Rolled Steel Coil

Overview of DC04 Cold Rolled Steel Coil

DC04 is an elite European standard cold-rolled low-carbon steel grade, specified under the EN 10130 norm as the benchmark for ‘Special Deep Drawing Quality’ (1.0338). Engineered for the most challenging forming applications, DC04 undergoes an intensive production process involving highly controlled cold reduction and specialized batch or continuous annealing. This results in a material with exceptionally low yield strength and unparalleled ductility, making it the industry standard for complex, deep-drawn components that require extreme material displacement without localized thinning or fracture.

Shandong Tanglu Metal Material Co., Ltd. supplies premium DC04 cold rolled coils designed for high-precision, high-complexity manufacturing. This grade is distinguished by its remarkable mechanical consistency and mirror-smooth surface finish, providing a flawless substrate for advanced robotic welding, high-gloss painting, and decorative electroplating. For B2B manufacturers in the automotive and premium appliance sectors, DC04 offers the technical performance necessary to execute intricate designs while maintaining the highest structural and aesthetic standards.

Key Features and Technical Advantages

The defining feature of DC04 cold rolled steel coil is its extraordinary elongation (typically ≥38% for A80 testing), which allows for the fabrication of deep-drawn parts that standard grades cannot achieve. With its precisely restricted carbon and alloy content, DC04 offers an extremely low yield-to-tensile ratio, ensuring that the material flows uniformly during the stamping process. It maintains exacting dimensional tolerances and an ultra-smooth surface finish, crucial for parts that require high-precision assembly and pristine surface cosmetics.

Our DC04 coils are supplied in the fully skin-passed condition, which guarantees a non-aging surface and prevents the formation of stretcher strains (Lüders lines) during the forming of large visible panels. The material’s consistent mechanical profile across the entire coil width ensures stable performance in automated, high-speed press lines, significantly reducing material waste and machine downtime. Whether in Matte or Bright finish, DC04 provides the technical foundation for the highest tiers of industrial metalworking.

Main Applications of DC04 Cold Rolled Coil

DC04 cold rolled steel coil is the primary choice for complex deep-drawn components in the automotive industry, including oil pans, fuel tanks, spare wheel wells, and intricate internal structural reinforcements. In the premium home appliance sector, it is essential for manufacturing complex washing machine drums, high-end refrigerator doors with deep-drawn handles, and specialized dishwasher liners that require significant metal stretching.

Beyond these sectors, DC04 is extensively utilized in the electronics industry for precision shielding covers, intricate computer chassis components, and specialized deep-drawn enclosures for high-performance hardware. It also serves as an elite substrate for advanced coated steel products, including high-spec electrolytic galvanized and prepainted coils intended for complex architectural shapes. Its unrivaled formability makes it the definitive choice for any manufacturing process where geometry and surface quality are the primary constraints.
