What is the difference between DC01 and DC03 steel?
DC01 can be used for simple forming work, for example Bending, embossing, beading and pulling. DC03 is suitable for forming requirements like Deep drawing and difficult profiles suitable.
What is DC03 steel?
DC03 is a low-carbon steel characterized by excellent cold formability. The chemical composition of DC03 is precisely defined to ensure that the material has the required mechanical properties. Typically, DC03 contains a maximum of 0.10% carbon, a maximum of 0.45% manganese and traces of phosphorus and sulphur.
What standard does GNEE's DC03 cold-rolled steel coil (1.0347) comply with?
GNEE's DC03 cold-rolled steel coil (material number: 1.0347) strictly adheres to the DIN EN 10130 standard, which is the European benchmark for cold-rolled low-carbon steel for cold forming. This compliance ensures consistent chemical composition, mechanical properties, and surface quality, making it suitable for global applications and international trade.
How is DC03 (1.0347) different from DC01 steel coil?
Compared to DC01 (the basic grade), DC03 (1.0347) offers superior deep drawability and ductility. Key differences include: DC03 has an elongation rate of ≥34% (vs. DC01's ≥28%) and a lower yield strength range (120-210 MPa vs. DC01's 140-280 MPa). This makes DC03 ideal for complex forming processes (e.g., shallow to medium deep drawing) in automotive and home appliance industries, while DC01 is better for simple bending or stamping.
What are the key mechanical properties of DC03 (1.0347) steel coil?
GNEE's DC03 (1.0347) features stable mechanical properties optimized for cold forming:
Yield Strength: 120-210 MPa
Tensile Strength: 270-350 MPa
Elongation (A80): ≥34%
Surface Roughness (Ra): ≤0.6 μm
These properties minimize cracking risks during complex stamping and ensure dimensional stability of finished products.
Can DC03 (1.0347) be used for automotive deep-drawing components?
Yes, it is an excellent choice for automotive shallow to medium deep-drawing parts. Typical applications include outer door panels, fenders, fuel tank shells, dashboard brackets, and radiator upper brackets. Its high elongation (≥34%) and low yield strength effectively withstand complex deformation, meeting the automotive industry's strict requirements for forming precision and reliability.
Does GNEE provide quality certificates for DC03 (1.0347) steel coil?
Absolutely. We provide EN 10204 Type 3.1 material test certificates for all DC03 (1.0347) shipments. This certificate includes actual test results of chemical composition, mechanical properties, and surface quality, certified by GNEE's quality department to ensure compliance with DIN EN 10130 standards-critical for customs clearance and downstream production quality control.
What is the minimum order quantity (MOQ) for DC03 (1.0347) steel coil?
The standard MOQ for GNEE's DC03 (1.0347) cold-rolled steel coil is 3 tons (per coil). For bulk orders (over 50 tons), we offer preferential pricing. We also accept small-batch orders (below 3 tons) for sample testing or trial production to support customers' initial project needs.
Can GNEE customize the specifications of DC03 (1.0347) steel coil?
Yes, we provide comprehensive customization services. Standard specifications include:
Thickness: 0.10-6.0 mm (customizable to 0.08 mm for special needs)
Width: 800-1500 mm (slitting to narrow widths available)

Additionally, we offer surface treatments such as skin passing to enhance flatness and paint adhesion.
What is the lead time for DC03 (1.0347) steel coil orders?
For standard specifications in stock, the lead time is 7-10 working days (from order confirmation to shipment). For customized orders or bulk quantities (over 100 tons), the lead time is 15-20 working days, depending on production scheduling. We prioritize urgent orders and provide real-time production updates to ensure on-time delivery.
Is DC03 (1.0347) suitable for home appliance components requiring painting?
Yes. DC03 (1.0347) has a smooth, scale-free surface (Ra≤0.6 μm) that ensures excellent adhesion of paints, coatings, or galvanizing layers. It is widely used for mid-to-high-end home appliance parts such as refrigerator curved door panels, washing machine inner drums, and air conditioner evaporator shells. The uniform material structure also guarantees consistent coating quality across the entire coil.
