DC01, DC02, DC03, DC04, DC05, and DC06 cold rolled steel plates are non-alloy low-carbon steels specified in DIN EN 10130, designed for different levels of cold forming and deep drawing performance.
As a professional cold rolled steel plate supplier and manufacturer, GNEE STEEL provides a complete range of EN 10130 DC grades in coil, sheet, and plate form, meeting the diverse requirements of automotive, appliance, electrical, and general fabrication industries.
The DC series steels are classified mainly by their formability:
- DC01–DC02: General forming quality
- DC03–DC04: Deep drawing quality
- DC05–DC06: Extra deep drawing quality
As the grade number increases, formability and ductility improve, while yield strength decreases.
Chemical Composition (Max, % – EN 10130)
| Grade | C | Mn | P | S |
|---|---|---|---|---|
| DC01 | 0.12 | 0.60 | 0.045 | 0.045 |
| DC02 | 0.10 | 0.60 | 0.035 | 0.035 |
| DC03 | 0.08 | 0.50 | 0.030 | 0.030 |
| DC04 | 0.08 | 0.50 | 0.025 | 0.025 |
| DC05 | 0.06 | 0.45 | 0.020 | 0.020 |
| DC06 | 0.04 | 0.40 | 0.020 | 0.020 |
Lower carbon and impurity levels provide better deep drawing performance.
Mechanical Properties (Typical)
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation A80 (%) | Formability |

| DC01 | ≤ 280 | 270–410 | ≥ 28 | General forming |
| DC02 | ≤ 260 | 270–410 | ≥ 30 | Improved forming |
| DC03 | ≤ 240 | 270–410 | ≥ 34 | Deep drawing |
| DC04 | ≤ 210 | 270–410 | ≥ 38 | Deep drawing |
| DC05 | ≤ 180 | 270–410 | ≥ 40 | Extra deep drawing |
| DC06 | ≤ 170 | 270–410 | ≥ 42 | Superior deep drawing |
Application Scenarios by Grade
DC01
Low-cost, general-purpose applications: Metal brackets, shelf supports, simple stamped parts, and non-critical structural components.
Ideal for industries where formability requirements are minimal (e.g., furniture, construction hardware).
DC02-DC03
Home appliances: Refrigerator door panels, TV backframes, air conditioner casings.
Electrical engineering: Switch boxes, cable trays, transformer covers.
Automotive: Non-structural parts (e.g., seat frames, mirror brackets).
DC04-DC05
Automotive: Deep-drawn parts (e.g., wheel arches, dashboard frames, fuel tank shells).
Machinery: Hydraulic cylinder casings, precision gears (after heat treatment).
DC06
High-end manufacturing: Complex automotive body panels (e.g., fenders, hoods), aerospace interior components.
Custom fabrication: Products requiring extreme shaping without material failure.

FAQ
Q1: What is the difference between DC03 and DC04?
A1: DC04 has lower carbon content (0.06% vs 0.08%) and higher elongation (34% vs 32%), making it suitable for deeper drawing. DC03 is cost-effective for medium-forming applications, while DC04 is preferred for complex shapes.
Q2: Can DC06 be welded?
A2: Yes. DC06's low carbon content (0.04%) ensures excellent weldability-compatible with MIG, TIG, and spot welding. Preheating is not required for thin sheets (<2mm).
Q3: Is DC05 suitable for outdoor use?
A3: Uncoated DC05 is prone to rust. For outdoor applications, choose galvanized (Zn-plated) or painted DC05 to enhance corrosion resistance.
Q4: What is the maximum deep drawing ratio for DC06?
A4: DC06 can achieve a drawing ratio of up to 2.2-2.5 (depending on sheet thickness), making it ideal for extreme shaping (e.g., cylindrical or conical parts).
Q5: How to select the right DC grade?
A5: Consider:
Forming complexity (simple bending → DC01/DC02; deep drawing → DC04-DC06).
Cost constraints (DC01 is the most economical; DC06 is premium).
Environmental conditions (coated grades for corrosion resistance).
