EN 10130 DC01 Steel 1.0330 cold rolled steel flat sheet coil
DC01 steel (1.0330 material) is a European standard cold-rolled quality low-carbon steel flat product for cold forming. In BS and DIN EN 10130 standard, it contains 5 other steel grades: DC03 (1.0347), DC04 (1.0338), DC05 (1.0312), DC06 ( 1.0873) and DC07 (1.0898), the surface quality is divided into 2 types: DC01-A and DC01-B. In addition, this steel is also used under electrogalvanizing conditions. The designation of the steel is DC01+ZE (or 1.0330+ZE), and the standard is EN 10152.

DC01+ZE Steel Mechanical Properties
The table below lists DC01+ZE steel mechanical properties.
| 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.Mechanical properties, Part-2
