Deep Drawing Cold Rolled Steel Sheet DC01 DC03 SPCC 0.3mm-3.0mm Stamping Coil For Auto Home Appliance

Deep drawing cold rolled steel sheet is produced by pickling hot rolled strip, cold rolling it to the required gauge, and annealing it in a controlled atmosphere to restore the soft, ductile structure that stamping dies need. The DC01, DC03, SPCC and SPCD grades we supply differ in their guaranteed drawability: DC01 and SPCC suit general forming and shallow drawn parts, while DC03 and SPCD provide the deeper drawability required for oil pans, sink bowls, battery cases and complex automotive panels. Because the surface is cold rolled to a smooth, defect free finish and protected by oil, the sheet also delivers the painted surface quality demanded by white goods and automotive exterior parts.

Stamping shops measure drawability not only by grade name but by consistency between coils, because a change in yield strength or r value between deliveries changes springback and can ruin a production run. Our coils come from integrated steel mills with tight control of annealing temperature and skin pass reduction, so the mechanical properties stay stable within each coil and from coil to coil. We can slit master coils to the exact width of your press line and supply sheets cut to blank size, with chemical treatment or oil film matched to your storage period. For critical draws our engineers work with your tool shop to select the grade that balances formability, strength after forming and cost.

• Soft annealed microstructure: controlled batch annealing gives the low yield strength and high elongation that deep drawing demands.
• Consistent drawability: stable mechanical properties between coils keep die setting and springback predictable in volume production.
• Smooth bright surface: cold rolled finish supports class A paint quality for automotive and appliance exterior panels.
• Choice of drawing grades: DC01 and SPCC for general forming, DC03 and SPCD for severe draws and complex geometry.
• Slit to line width: master coils are slit and rewound to the exact width of your press feed, reducing edge scrap.
• Surface protection options: oiled, dry or chemically treated surfaces match your storage and welding requirements.

Deep drawing cold rolled steel sheet feeds press lines that produce automotive body panels, fuel tanks, seat parts and wheel housings, home appliance shells for washing machines, refrigerators and microwave ovens, kitchen sinks, cookware, battery cases for power tools and electric vehicles, office furniture panels, lighting housings and countless drawn and stamped components in the hardware and electronics industries. The coil is also the starting stock for porcelain enameled parts such as bathtubs and cooktop trays, where the clean surface and controlled carbon level support defect free enameling.

Coils are wound on steel cores with inner and outer edge protection, wrapped in moisture barrier paper and packed for container shipment with the eye vertical or horizontal as agreed. Cut sheets are palletized with interleaving paper and corner protection. Quality documentation includes the mill certificate with chemical composition, yield and tensile strength, elongation, hardness and surface roughness readings, and we can arrange restricted specification checks by third party inspectors.
