DC01 steel (1.0330 material) is a European standard cold-rolled quality low-carbon steel flat product for cold forming.
Steel Grade of DC01 Steel
DC01-A: Allow defects that do not affect formability or surface coating, such as pores, slight dents, small marks, slight scratches, and slight coloring.
DC01-B: Better surfaces shall be free from defects that may affect the uniform appearance of high-quality paints or electrolytic coatings. The other surface should meet at least surface quality A.
DC01+ZE: Electrolytically zinc coated
DC01EK: Conventionally enamelled
DC01 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.
