Products Description
DC01 is one of the most commonly used cold rolled steel grades in the global steel market. Known for its excellent surface quality, stable mechanical properties, and good formability, DC01 is widely applied in automotive components, household appliances, electrical enclosures, metal furniture, and general fabrication industries. Because steel procurement often involves international sourcing, understanding the DC01 grade equivalent chart across different standards is essential for engineers, buyers, and manufacturers.
What Is DC01 Cold Rolled Steel?
DC01 is a low-carbon cold rolled steel grade defined under the EN 10130 standard. It is designed for cold forming and general-purpose applications where good surface finish and consistent mechanical performance are required. The cold rolling process improves dimensional accuracy and surface smoothness compared to hot rolled steel, making DC01 suitable for coated, painted, and decorative parts.
DC01 steel (1.0330 material) is a European standard cold-rolled quality low-carbon steel flat product for cold forming. In BS and DIN EN 10130 standard, it contains 5 other steel grades: DC03 (1.0347), DC04 (1.0338), DC05 (1.0312), DC06 ( 1.0873) and DC07 (1.0898), the surface quality is divided into 2 types: DC01-A and DC01-B. In addition, this steel is also used under electrogalvanizing conditions. The designation of the steel is DC01+ZE (or 1.0330+ZE), and the standard is EN 10152.

DC01 Steel Equivalent Grades Table
| Standard System | Equivalent Grade | Description |
|---|---|---|
| EN 10130 | DC01 | Cold rolled mild steel for general forming |
| DIN | St 12 | Cold forming steel with similar strength and ductility |
| ASTM | A1008 CS Type B | Commercial-quality cold rolled steel |
| JIS | SPCC | Cold rolled commercial steel |
| GB (China) | Q195 / SPCC | Low-carbon cold rolled steel |
| ISO | CR1 | Cold rolled steel for general applications |
This DC01 equivalent chart helps buyers confidently substitute materials when sourcing cold rolled steel from different regions.
Chemical Composition Comparison
Although equivalent grades share similar performance, their chemical limits may vary slightly between standards.
Typical Chemical Composition of DC01
| Element | Max Content (%) |
|---|---|
| Carbon (C) | ≤ 0.12 |
| Manganese (Mn) | ≤ 0.60 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.045 |
| Nitrogen (N) | ≤ 0.009 |
The low carbon content contributes to excellent formability and surface quality, which are key characteristics of DC01 and its equivalent grades.
Mechanical Properties of DC01 and Equivalent Grades
Mechanical Property Reference Table
| Property | Typical Range |
|---|---|
| Yield Strength | 140–280 MPa |
| Tensile Strength | 270–410 MPa |
| Elongation (A80) | ≥ 28% |
| Hardness | ≤ 65 HRB |
These values demonstrate why DC01 steel and its equivalents are classified as commercial-quality cold rolled steels suitable for a wide range of forming operations.

FAQ：
1. What is DC01 cold rolled steel used for?
DC01 is widely used for general forming applications such as metal furniture, electrical cabinets, steel drums, and simple stamped parts where high formability is not required.
2. What is the difference between DC01 and DC03?
DC03 offers better deep drawing performance than DC01. It is more suitable for complex stamping and forming processes, while DC01 is used for basic bending and light forming.
3. Is cold rolled steel suitable for deep drawing?
Yes, certain grades such as DC03, DC04, DC05, and DC06 are specifically designed for deep drawing and extra-deep drawing applications.
4. What thickness range is available for cold rolled steel sheets?
Cold rolled steel sheets are commonly available in thicknesses ranging from 0.3 mm to 3.0 mm, depending on the grade and standard.
