DC01 Cold Rolled Steel
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.
Cold Rolled Steel
Due to its moderate strength and good elongation, DC01 is ideal for bending, profiling, stamping, and light drawing operations. For deeper drawing requirements, higher grades such as DC03, DC04, or DC05 are typically selected.
DC01 Grade Equivalent Chart
The following table compares DC01 steel equivalents across major international standards. While the grades are not always chemically identical, they offer comparable mechanical performance and application suitability.
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.
Applications of DC01 and Its Equivalent Grades
DC01 and equivalent cold rolled steel grades are widely used in industries requiring smooth surface finish and stable forming behavior. Typical applications include:
Automotive interior components and brackets
Household appliance panels and housings
Electrical cabinets and control boxes
Metal furniture and shelving systems
HVAC ducts and construction profiles
General fabrication and stamping parts
The wide acceptance of DC01 equivalents makes it easier for manufacturers to adapt to different market standards without changing production processes.
