DC01 (GB) is a widely used cold rolled low-carbon steel known for its excellent surface quality, good formability, and cost efficiency. In the Chinese GB system, DC01 is commonly supplied as SPCC under GB/T 5213, and it is fully equivalent to EN 10130 DC01 for general cold forming applications.
As a professional steel supplier, GNEE STEEL provides DC01 (GB) steel in sheet, plate, and coil form for global industrial customers.
What Is DC01 (GB) Steel?
DC01 is a non-alloy cold rolled mild steel designed for general forming purposes such as bending, light stamping, and profiling.
In China, DC01 is usually produced and supplied according to GB/T 5213 (SPCC), while maintaining the same chemical and mechanical requirements as EN 10130 DC01.
It is not intended for deep drawing; grades like DC03 or DC04 are recommended for more complex forming.
Chemical Composition (GB/T 5213-2019)
| Element | Maximum Content (%) | Effect |
|---|---|---|
| Carbon (C) | ≤0.12 | Ensures good formability and weldability |
| Manganese (Mn) | ≤0.60 | Provides moderate strength |
| Phosphorus (P) | ≤0.045 | Controls brittleness |
| Sulfur (S) | ≤0.045 | Minimizes hot cracking during processing |
| Silicon (Si) | ≤0.03 | Kept low to maintain ductility |
| Aluminum (Al) | ≤0.02 | Deoxidizer, improves surface quality |
Mechanical Properties
| Property | Value | Significance |
|---|---|---|
| Yield Strength | 140-280 MPa | Deforms predictably under load |
| Tensile Strength | 270-410 MPa | Ultimate resistance to breaking |
| Elongation (A80) | ≥28% | High ductility, ideal for cold forming |
| Rockwell Hardness | 50-70 HRB | / |
| Vickers Hardness | 90-130 HV | Surface resistance to indentation |
| Elastic Modulus | 210 GPa | Stiffness, minimal deformation under load |
Note: Thickness affects properties:
For thickness ≤0.7mm >0.5mm: Yield strength may increase by 20 MPa, elongation decrease by 2%
For thickness ≤0.5mm: Yield strength may increase by 40 MPa, elongation decrease by 4%

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.
