DC01 vs DC04 Cold-Rolled Steel Coils: Key Differences and Applications
- John
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.
Chemical Compositions of DC01 vs DC04
| Grade | C | Mn | P | S |
| DC01 | ≤0.12 | ≤0.60 | ≤0.045 | ≤0.045 |
| DC04 | ≤0.08 | ≤0.40 | ≤0.030 | ≤0.030 |
Mechanical Properties of DC01 vs DC04
| Property | DC01 | DC04 |
| Yield Strength (MPa) | ≤ 280 | ≤ 210 |
| Tensile Strength (MPa) | 270 – 410 | 270 – 350 |
| Elongation (%) | ≥ 28 | ≥ 38 |
| Anisotropy (r90) | – | ≥ 1.6 |
| Hardening Exponent (n90) | – | ≥ 0.18 |
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.
