Cold-rolled steel DC04 vs DC01
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.
Chemical composition
The chemical composition influences the formability and weldability of the steel. Both steels are made of carbon steel, but DC04 has a lower carbon content, which supports its improved cold formability. Thanks to the lower carbon and sulphur content, DC04 offers improved deep-drawing capability as less intergranular embrittlement occurs.
Mechanical properties
The mechanical properties are decisive for the forming processes and the behavior of the steel under load. DC04 has a lower yield strength and higher elongation, which makes the material easier to form. The lower yield strength and increased minimum elongation of DC04 make this material ideal for demanding forming processes such as deep drawing.
| Element | DC01 (max. %) | DC04 (max. %) |
|---|---|---|
| Carbon (C) | 0,12 | 0,08 |
| Manganese (Mn) | 0,60 | 0,40 |
| Phosphorus (P) | 0,045 | 0,030 |
| Sulphur (S) | 0,045 | 0,030 |
| Characteristics | DC01 | DC04 |
|---|---|---|
| Yield strength (MPa) | ≤ 280 | ≤ 210 |
| Tensile strength (MPa) | 270-410 | 270-350 |
| Elongation (at 80mm, %) | ≥ 28 | ≥ 38 |
Areas of application
Both steels are used in many branches of industry, but they differ in terms of their optimum areas of application:
DC01
– Housing and cladding parts
– Simple formed parts
– Structural components with a low degree of deformation
DC04
– Deep-drawn components with high shape complexity
– Vehicle body parts
– Household appliances with high surface requirements
It can be said that the special deep-drawing grade DC04 offers a wide range of applications in accordance with both DIN EN 10130 and DIN EN 10152. While DIN EN 10130 focuses on high formability and surface quality, DIN EN 10152 supplements these properties with improved corrosion resistance thanks to the zinc coating. Both standards ensure that DC04 is a reliable and high-quality material for numerous industrial applications.
