DC01 steel is a widely used cold rolled low-carbon mild steel specified under EN 10130. It is designed for general cold forming applications, such as bending, light stamping, profiling, and surface-treated components.
Because DC01 is extensively traded internationally, understanding its equivalent materials in ASTM, JIS, DIN, GB, and ISO standards is essential for material substitution, procurement, and export projects.
What Is DC01 Steel?
DC01 is a non-alloy cold rolled steel grade with:
Low carbon content
Good surface quality
Stable mechanical properties
Excellent workability
It is not a deep drawing grade. Instead, DC01 sits at the entry level of the EN 10130 DC series:
DC01 → DC02 → DC03 → DC04 → DC05 → DC06
(Formability increases as the grade number increases)
Main Equivalent Grades of DC01 Steel
🌍 International Equivalents Overview
| Standard | Grade | Description |
|---|---|---|
| EN 10130 | DC01 | European cold rolled steel |
| DIN (old) | St12 | Traditional German designation |
| JIS G 3141 | SPCC | Japanese commercial-quality CR steel |
| ASTM A1008 | CS Type B | US cold rolled commercial steel |
| GB/T 5213 | SPCC | Chinese GB cold rolled steel |
| ISO 3574 | CR1 | International cold rolled commercial quality |
These grades are considered functionally equivalent, meaning they can usually replace DC01 in general forming applications, subject to technical confirmation.
Chemical Composition Comparison (Typical / Max %)
| Grade | C | Mn | P | S |
|---|---|---|---|---|
| DC01 | ≤ 0.12 | ≤ 0.60 | ≤ 0.045 | ≤ 0.045 |
| SPCC (JIS) | ≤ 0.12 | ≤ 0.60 | ≤ 0.045 | ≤ 0.045 |
| St12 (DIN) | ≤ 0.12 | ≤ 0.60 | ≤ 0.045 | ≤ 0.045 |
| A1008 CS-B | ≤ 0.15 | ≤ 0.60 | ≤ 0.030 | ≤ 0.035 |
👉 Low carbon content is the key reason these steels show similar forming and welding behavior.
Mechanical Properties Comparison (Typical)
| Property | DC01 | SPCC | A1008 CS-B |
|---|---|---|---|
| Yield Strength | ≤ 280 MPa | ~240–280 MPa | ~170–280 MPa |
| Tensile Strength | 270–410 MPa | 270–410 MPa | 270–410 MPa |
| Elongation (A80) | ≥ 28% | ≥ 28% | ≥ 28% |
✔ These overlapping ranges allow DC01 to be safely substituted in most non-critical applications.
Why DC01 Has So Many Equivalents
DC01 belongs to a global class of cold rolled commercial-quality steels, which share the same industrial purpose:
Simple forming, not deep drawing
Good surface appearance
Easy welding and machining
Cost efficiency for mass production
Different standards use different naming systems, but the metallurgical philosophy is the same.
Application-Based Equivalence (Very Important)
DC01 equivalents can usually replace each other for:
Electrical cabinets and enclosures
Appliance panels
Furniture components
Metal brackets and covers
Automotive interior and non-structural parts
Knife handles, liners, stamped metal parts
DC01 vs Deep Drawing Equivalents (Quick Clarification)
| Grade | Forming Level |
|---|---|
| DC01 / SPCC / St12 | General forming |
| DC03 / SPCD / St13 | Deep drawing |
| DC04 / SPCE / St14 | Deep drawing (higher ductility) |
Many buyers mistakenly assume SPCC = DC04.
❌ This is incorrect.
✔ SPCC ≈ DC01, not DC04.
Certification & Substitution Notes for Export
When using DC01 equivalents in international projects:
Always confirm standard reference
Check thickness-dependent properties
Request EN 10204 3.1 / Mill Test Certificate
State substitution clearly in contracts and drawings
Example:
"Material: EN 10130 DC01 or equivalent (JIS SPCC / ASTM A1008 CS-B)"
Summary: What Is DC01 Steel Equivalent To?
DC01 steel is equivalent to:
SPCC (JIS G 3141)
St12 (DIN – old)
ASTM A1008 CS Type B
GB/T 5213 SPCC
ISO 3574 CR1
All are cold rolled low-carbon steels for general forming, with similar composition, mechanical properties, and applications.

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.
