DC04 Deep Drawing Cold Rolled Steel Coil
DC04 is a high-quality deep-drawing grade cold-rolled low-carbon steel defined in the European standard EN 10130. Its core value lies in the deep-drawing performance and surface quality far exceeding that of ordinary cold-rolled sheets through precise cold-rolling process and annealing treatment, which is particularly suitable for the manufacture of parts requiring complex deformation processing.
Mechanical properties (typical values according to EN 10130)
Yield strength (Rp0.2): 120 - 240 MPa (depending on thickness and condition)
Tensile strength (Rm): 270 - 350 MPa
Elongation at break (A80mm): ≥ 34% (generally higher for thickness ≤ 2mm)
Plastic strain ratio (r-value): ≥ 1.8 (average value, reflecting resistance to thinning)
Work hardening index (n-value): ≥ 0.20 (reflecting uniform deformation ability)
In the wave of the automotive industry's transformation towards lightweight, DC04 cold rolled steel coil has demonstrated its irreplaceable value:
Thin gauge breakthrough: Handan Iron and Steel successfully rolled 0.5mm ultra-thin plates for automotive inner panels and small structural parts, reducing weight by more than 30% compared to traditional materials.
Manufacturing of complex parts: Stamping parts with complex curved surfaces such as side panels, roofs, and floors rely on its high elongation to form in one go.
Energy-saving benefits: For every ton of thin gauge DC04 plates used, the vehicle weight is reduced by about 15kg, and fuel consumption per 100 kilometers is reduced by 0.1 liters.
GNEE Steel have established long-term strategic cooperation with well-known large steel mills to ensure that the source quality of DC04 cold-rolled coils is reliable and the performance strictly complies with EN 10130 and customer-specific standards.
Each batch of materials comes with a complete original manufacturer's warranty (MTC) and is traceable.
