In modern industrial applications, selecting the right cold rolled steel is crucial for stamping, bending, and deep drawing components. Two widely used steel types are DC03 steel coil (DIN EN 10130 standard) and ASTM A1008 cold rolled steel. Understanding their chemical properties, mechanical performance, and application suitability is essential for manufacturers in automotive, appliance, electrical, and furniture industries.
At GNEE Steel, we provide high-quality DC03 steel coils that meet international standards, delivering precision, durability, and consistency for various multi-industry applications.
Chemical Composition Comparison
Both DC03 and ASTM A1008 are low-carbon cold rolled steels designed for excellent formability and smooth surface finish. Below is a typical chemical composition comparison:
| Element | DC03 (DIN EN 10130) | ASTM A1008 | Notes |
|---|---|---|---|
| Carbon (C) | ≤0.15% | ≤0.12–0.15% | Low carbon content ensures high ductility and formability |
| Manganese (Mn) | ≤0.90% | 0.30–0.60% | Supports tensile strength and moderate hardness |
| Silicon (Si) | ≤0.40% | 0.03–0.10% | Acts as a deoxidizer and improves surface finish |
| Phosphorus (P) | ≤0.045% | ≤0.04% | Low P reduces brittleness |
| Sulfur (S) | ≤0.045% | ≤0.05% | Low S minimizes cracking during forming |
Observation: DC03 allows slightly higher manganese, providing better strength for complex forming, while ASTM A1008 maintains a slightly cleaner chemical profile suitable for coating or painting processes.
Mechanical Properties Comparison
Mechanical performance is a key factor for stamping and bending components:
| Property | DC03 | ASTM A1008 | Application Impact |
|---|---|---|---|
| Yield Strength (Re) | 180–320 MPa | 170–280 MPa | DC03 provides slightly higher yield strength for structural stability during forming |
| Tensile Strength (Rm) | 280–450 MPa | 270–400 MPa | DC03 offers higher tensile strength for heavier-duty stamping |
| Elongation (A) | ≥26% | ≥28% | ASTM A1008 is slightly more ductile, favorable for deep drawing without cracks |
| Surface Finish | Smooth cold-rolled | Smooth cold-rolled | Both suitable for painted or coated finishes |
Key Insight: DC03 is optimized for balanced strength and formability, while ASTM A1008 offers slightly higher ductility, ideal for ultra-deep drawing applications.

Which is better DC01 or AISI 1008 steel?
DC01 (European standard) and AISI 1008 (American standard) are both ultra-low carbon steels with similar composition (C≤0.1%), but DC01 is optimized for deep drawing, has higher elongation, and is suitable for complex automotive stampings; AISI 1008 is more versatile, has slightly higher strength, and is suitable for ordinary hardware.
Is AISI 1008 the same as ASTM A607?
AISI 1008 and ASTM A607 are not the same. They belong to different standard systems. AISI 1008 is ordinary low-carbon steel, which is used in low-strength scenes such as cold-formed parts, bolts, and simple stampings. ASTM A607 is high-strength low-alloy steel, which is used for structural parts that require high strength (such as vehicle chassis and building supports), and has both weldability and formability.
What is AISI 1008?
AISI 1008 is a low carbon steel in the American Iron and Steel Institute standard. It is an ordinary carbon steel with low strength, excellent plasticity and ductility, and is suitable for cold processing such as deep drawing and bending.
In what fields can AISI 1008 be used?
AISI 1008 can withstand complex forming processes such as deep drawing and stretching without cracking, and can be used for car door inner panels and washing machine panels. It also has excellent weldability and can be used as storage shelves and simple guardrails. Its low carbon content significantly reduces the risk of weld cracks, and it does not require preheating and can be easily cut and bent.
What is AISI 1008 specification?
The core specification of AISI 1008 is ultra-low carbon + low alloy, which is suitable for scenarios requiring high formability and low cost. When selecting materials, it is necessary to combine the specific form (plate, wire, tube) and processing technology (cold rolling, welding) to match the corresponding standards (such as ASTM A568)
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

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.
