DC01 and DC04 are both cold-rolled steels but have different levels of formability. DC01 offers standard formability, making it suitable for simpler shapes in general applications. DC04, however, has higher formability, ideal for more complex or deep-drawn parts where intricate shaping is needed.

Different performance of DC01 vs DC04
Corrosion Resistance
DC01 and DC04 steels have a limited natural resistance to corrosion because they lack alloying elements like chromium or nickel. Protective coatings are essential for their long-term durability.
One of the most common surface treatments for DC01 and DC04 is zinc coating, especially electro-galvanizing. Electro-galvanizing applies a smooth, even layer of zinc that protects the steel from rust and is ideal for automotive exteriors.
Formability
DC04 has significantly better formability than DC01. DC04 can withstand complex shaping and deep-drawing processes without cracking. DC01 is ideal for simple forming processes such as bending, shallow drawing, and stamping.
Cost
DC04 generally costs more than DC01 because it undergoes additional processing to enhance its formability. In contrast, DC01 is a standard grade that requires less processing, making it a more economical option for applications where basic shaping is sufficient.
Application
DC01 and DC04 are widely used in manufacturing but serve different applications. Both materials are available in forms such as cold-rolled steel sheets and coils, making them versatile choices across various industries.
DC01
Automotive Industry: Interior panels, brackets, and components that do not require extreme shaping.
Appliance Manufacturing: Basic parts for refrigerators, washing machines, and ovens.
Furniture Production: Metal frameworks, cabinets, and shelving where moderate strength and surface quality are needed.
Construction: Panels, metal enclosures, and ducts in building projects requiring reliable, formable steel.
DC04
Automotive Industry: Exterior body panels, door frames, and other complex-shaped components that require deep drawing.
Appliance Manufacturing: Detailed parts for appliance exteriors and control panels, where high formability and smooth surfaces are essential.
Precision Metal Parts: Intricate items such as casings and housings for electronics and machinery.
Household and Office Furniture: Sleek, complex metal designs for high-end furniture and office decor.
DC01 vs DC04: How to Choose?
Choose DC01 if:
Parts involve simple bending or stamping
Deep drawing is not required
Cost control is a priority
Choose DC04 if:
Parts require deep drawing or complex shapes
Surface quality and dimensional stability are critical
Multi-stage forming processes are used

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.
