DC01 steel
The prevalence and popularity of DC01 steel grades all about the everyday applications of cold rolled steel, as characterized by an exceptional appearance, working properties and consistency. Applications such as automobile, construction, and homemakers use these steels because they are easy to form, weld, and include names. This steel is unfailingly flat and relatively stiff, which makes it ideal for most equipment and devices where precision and high strength are of the essence. The consequence of its sleek nature is that this steel grade permits painting and other surface finishes without compromising the application or the esthetic needs of the structure.
Chemical Composition
DC01 steel chemical composition is listed in the following table based on ladle analysis.
| Country (Region) | Standard | Chemical Composition (ladle analysis), %, ≤ | Surface quality | Deoxidation | Classification | ||||
| Steel name (Steel number) | C | Mn | P | S | |||||
| European Union | EN 10130 | DC01 (1.0330) | 0.12 | 0,60 | 0,045 | 0,045 | A, B | Manufacturer's discretion | Non-alloy quality steel |
| EN 10152 | DC01+ZE (1.0330+ZE) | A, B | |||||||
| EN 10139 | DC01-C390, C340, C440, C490, C590, C690 | – | |||||||
Notes:
EN 10130 – Cold rolled low carbon steel flat products;
EN 10152 – Electrolytically zinc coated cold rolled steel flat products.
EN 10139 – Cold rolled uncoated low carbon steel narrow strip.
DC01 vs S235: Key Differences Overview
The table below provides a quick comparison of key differences between DC01 and S235.
| Feature | DC01 (Cold-Rolled Steel) | S235 (Structural Steel) | ||
| Main Use | Formability & surface quality (automotive, appliances) | Strength & durability (construction, frameworks) | ||
| Strength | Lower yield strength (140-280 MPa) | Higher yield strength (235 MPa) | ||
| Formability | High – excellent for bending & shaping | Moderate – more rigid for load-bearing | ||
| Corrosion Resistance | Low – requires coatings for protection | Slightly better due to added copper | ||
| Appearance | Smooth, clean surface | Industrial finish, visible mill scale | ||
| Cost | Higher due to cold-rolling process | Lower, optimized for mass structural use | ||
