DC01 Cold-Rolled Galvanized Coil
Industrial Material: DC01 is a cold-rolled low-carbon steel grade (European Standard EN 10130), commonly used in automotive manufacturing and sheet metal processing.
Code or Model: Certain equipment, experiments, or military/technical projects may use "DC01" as a code (such as drone model, experimental number, etc.).
What is DC01 Cold-Rolled Galvanized Coil?
DC01 Cold-Rolled Galvanized Coil is a common cold-rolled low-carbon steel galvanized coil, a material grade specified in the European Standard (EN 10130). It is primarily used in the automotive, home appliance, and construction industries. The following is a detailed description:
1. Material Standards and Classifications
Standard: EN 10130 (European Standard for Cold-Rolled Low Carbon Steel)
Grade: DC01 (corresponding to Chinese grade SPCC, Japanese grade JIS SC1, and the US equivalent grade ASTM A1008 CS Type B)
Surface Treatment: Hot-Dip Galvanizing (GI) or Electrogalvanizing (EG). Common zinc coating codes include Z60 (60g/m²) and Z80 (80g/m²).
2. Main Performance Characteristics
Base Material Characteristics:
Low carbon steel (C ≤ 0.12%), good plasticity, and easy to stamp and bend.
The cold rolling process results in a smooth surface and uniform thickness (common thickness 0.3-3.0mm).
Purpose of the Galvanized Coating:
Corrosion and rust prevention, extending service life (the thicker the zinc coating, the greater the corrosion resistance).
3. Typical Applications:
Automotive Industry: Body panels, interior trim, etc.
Home Appliances: Refrigerator housings, air conditioner panels, etc.
Construction: Light steel keels, ventilation ducts, etc.
Other: Office furniture, electronic equipment housings, etc.
4. Common Technical Parameters
Item Parameter Example
Tensile Strength (MPa) 270-410
Yield Strength (MPa) ≥140 (depending on heat treatment status)
Elongation (%) ≥28 (gauge length 80mm)
Galvanized Layer Weight Z60/Z80/Z120 (g/m²)
5. Comparison with Other Grades
DC01 vs. DC04/DC06:
DC01 is a general stamping grade, while DC04/DC06 are deep drawing grades (with higher elongation, suitable for complex formed parts).
DC01 vs. DX51D:
DX51D is a base grade specifically for galvanizing (EN 10346), while DC01 is a cold-rolled base grade. After galvanizing, it may be marked as DC01+Z.
6. Purchasing Considerations
Specify requirements: thickness, galvanizing (single/double-sided), and surface treatment (e.g., passivation, oiling, etc.).
Standard certification: Compliance with EN 10130 or customer-specified standards (e.g., TS 16949 for automotive manufacturers).
