DC01 and DC04 are both cold rolled low-carbon steels defined in EN 10130, but they are designed for very different forming requirements.
The key difference lies in formability:
DC01 = general forming
DC04 = deep drawing
| Item | DC01 | DC04 |
|---|---|---|
| Standard | EN 10130 | EN 10130 |
| Steel type | Cold rolled mild steel | Cold rolled deep-drawing steel |
| Forming level | General forming | Deep drawing |
| Typical supply | Coil / sheet / plate | Coil / sheet / plate |
Chemical Composition
| Element | DC01 (≤%) | DC04 (≤%) | Impact |
|---|---|---|---|
| Carbon (C) | 0.12 | 0.08 | Lower carbon in DC04 enhances ductility and weldability |
| Manganese (Mn) | 0.60 | 0.40 | Reduced Mn in DC04 improves formability |
| Phosphorus (P) | 0.045 | 0.030 | Lower P limits brittleness in DC04 |
| Sulfur (S) | 0.045 | 0.030 | Reduces hot cracking during processing in DC04 |
Mechanical Properties
| Property | DC01 | DC04 | Significance |
|---|---|---|---|
| Yield Strength (MPa) | 140-280 | 120-210 | DC04 has lower yield strength, making it easier to deform |
| Tensile Strength (MPa) | 270-410 | 270-350 | DC01 has slightly higher tensile strength |
| Elongation (%) | ≥28 | ≥38 | DC04 exhibits 36% higher elongation, crucial for deep drawing |
| Plastic Strain Ratio (r90) | ≥1.3 | ≥1.6 | DC04 has better anisotropy resistance, ideal for complex forming |
| Strain Hardening Index (n90) | ≥0.18 | ≥0.20 | DC04 shows superior work-hardening capability |
Formability & Performance
DC01:
Standard formability - suitable for simple bending, shallow drawing

Cost-effective for general-purpose forming needs
DC04:
Superior formability - designed specifically for deep drawing operations
Can withstand severe deformation without cracking
Excellent for intricate shapes requiring high dimensional accuracy
Higher production cost due to additional processing
Applications
DC01 Best Uses:
Appliance manufacturing: Basic parts (refrigerator panels, washing machine shells)
Automotive industry: Interior panels, brackets, non-structural components
Construction: Simple wall/roof panels, ducts
Furniture: Metal frameworks, cabinets
General fabrication: Simple stamped parts
DC04 Best Uses:
Automotive: Exterior body panels (doors, hoods, fenders), fuel tanks

Precision metal components: Electronic enclosures, device casings
High-end furniture: Sleek, complex metal designs
Industrial equipment: Parts requiring intricate forming
How to Choose: DC01 or DC04?
Choose DC01 if:
Parts involve simple bending or light stamping
Deep drawing is not required
Cost is the main concern
Choose DC04 if:
Parts require deep drawing or complex shapes
Multi-stage stamping is used
Surface quality and dimensional stability are critical

What is the difference between DC01 and DC04 steel?
DC04 and DC01 are both cold-rolled, unalloyed quality steels that are used for various industrial applications. While DC01 serves as the standard grade for general cold forming processes, DC04 is characterized by improved deep-drawing properties and higher ductility.
Is DC01 the same as CR4?
Cold Reduced steel
Here at GNEE Steel, we stock and process DC01 mild steel (often referred to as CR4), in varying thicknesses from 0.9mm up to 3mm. Each sheet is de-coiled and flattened to strict tolerances in our works, ensuring consistent quality and flatness, every time.
What does DC01 mean?
DC01 represents the basic grade of the DC steel family and is also known under the former designations St12 or FeP01. This grade can be used for simple forming operations such as bending, coining, beading and drawing.
What is the difference between DC01 and DC03?
DC01 – This grade can be used for simple forming work, e.g. bending, embossing, beading and drawing. DC03 – This grade is suitable for forming requirements such as deep drawing and difficult profiling.
What is DC01 steel equivalent to?
Material 1.0330, DC01 steel equivalent to ASTM, ISO, European (German DIN, British BSI, France NF), Japanese JIS and Chinese GB standard (for reference). Note: DIN 1623 has been replaced by DIN EN 10130, and the designation ST12 has been replaced by DC01.
What is the thickness of DC01 material?
Galvanized Steel Sheet - Grade Dc01, Thickness 0.2-3.50mm, Width 914-1250mm | Cold Rolled, Durable Zinc Coating, Long Lasting Toughness.
Is cold-rolled steel better than hot rolled steel?
Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling. It is also up to 20% stronger than hot rolled through the use of strength hardening.
