DC01 Steel Data Sheet
What Is DC01 Steel?
DC01 steel is a cold-rolled, low-carbon steel defined according to European standard EN 10130. It belongs to the DC (cold-drawn) steel family, where "DC" denotes suitability for cold forming, and "01" designates the basic quality grade. DC01 is an unalloyed steel whose clean surface and uniform microstructure make it particularly suitable for secondary processes such as coating, painting, electroplating, and welding. However, DC01 lacks inherent corrosion resistance.
The tables and lists below give grade DC01 steel data sheet and specification including chemical composition, mechanical properties, welding, etc.
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 |

DC01+ZE Steel Mechanical Properties
The table below lists DC01+ZE steel mechanical properties.
| Mechanical properties, Part-1 | |||||||
| Country (Region) | Standard | Steel name (Steel number) | Yield strength (MPa), 0.2 % offset | Tensile strength (MPa) | Elongation, ≥ % | Surface quality | Absence of stretcher strain marks |
| European Union | EN 10130 | DC01 (1.0330) | 140 (assumed) -280 | 270-410 | 28 | A, B | – |
| EN 10152 | DC01+ZE (1.0330+ZE) | 3 months | |||||
Notes:
Yield strength: When the thickness is ≤0.7 mm but >0.5 mm, the yield strength value should be increased by 20 MPa. For thicknesses ≤0.5 mm, the value should be increased by 40 MPa.
Elongation: When the thickness is ≤0.7 mm but >0.5 mm, the minimum value of elongation should be reduced by 2 units. For thicknesses ≤0.5 mm, the minimum value shall be reduced by 4 units.
