DC01 is a European standard, non-alloy, cold-rolled, low-carbon steel known for its excellent ductility, formability (bending, stamping, deep drawing), smooth surface, and good weldability, often used in automotive, appliance, and general engineering for parts needing good finish and shaping without high strength requirements. It's the basic grade in the DC series, offering great machinability and workability due to its low carbon content (≤0.12%).

Cold rolled steel is also part of our product portfolio. Cold rolled steel is excellent for cold forming. This product group assigned the grades DC01 to DC07, DC01EK to DC06EK, DC03ED to DC06ED and S215G to S325G.
The grades are classified according to the maximum permissible yield strength and can be subdivided as follows.
DC01 – This grade can be used for simple forming work, for example Bending, embossing, beading and pulling are used.
DC03 – This grade is suitable for forming requirements such as Deep drawing and difficult profiles suitable.
DC04 – This quality is suitable for high deformation requirements.
DC05 – This thermoforming grade is suitable for higher forming requirements.
DC06 – This special deep drawing quality is suitable for the highest deformation requirements.
DC07 – This super deep drawing quality is suitable for extreme deformation requirements.
Enamelled grades
The steel grades DC01EK, DC04EK and DC06EK are suitable for conventional single-layer or double-layer enamelling.
The steel grades DC06ED, DE04ED and DC06ED are suitable for direct enamelling as well as for enamelling according to the two-layer / one-firing method and for special applications of two-layer enamelling for low-distortion enamelling.
Surface type
Surface A
Mistakes such as pores, small grooves, small warts, slight scratches and a slight discoloration that does not affect the ability to reshape and adhere to surface coatings are permitted.
Surface B
The better side must be free from defects so that the homogeneous appearance of a quality finish or an electrolytically applied coating is not impaired. The other side must at least meet the requirements of surface type A.
Surface finish
The surface finish may be particularly smooth, dull or rough. If no details are given when ordering, the surface finish will be delivered in a matt finish. The four surface finishes listed correspond to the center roughness values in the following table and must be tested in accordance with EN 10049.
| Surface finish | characteristic | Average surface finish (boundary value: 0,8mm) |
| Special flat | b | Ra ≤ 0,4 µm |
| flat | g | Ra ≤ 0,9 µm |
| Matt | m | 0,60 µm ˂ Ra ≤ 1,9 µm |
| rough | r | Ra ≤ 1,6 µm |

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.
