What is the difference between DC01 and DC03 steel?
DC01 can be used for simple forming work, for example Bending, embossing, beading and pulling. DC03 is suitable for forming requirements like Deep drawing and difficult profiles suitable.
What is DC03 steel?
DC03 is a low-carbon steel characterized by excellent cold formability. The chemical composition of DC03 is precisely defined to ensure that the material has the required mechanical properties. Typically, DC03 contains a maximum of 0.10% carbon, a maximum of 0.45% manganese and traces of phosphorus and sulphur.
What standard does GNEE's DC03 cold-rolled steel coil (1.0347) comply with?
GNEE's DC03 cold-rolled steel coil (material number: 1.0347) strictly adheres to the DIN EN 10130 standard, which is the European benchmark for cold-rolled low-carbon steel for cold forming. This compliance ensures consistent chemical composition, mechanical properties, and surface quality, making it suitable for global applications and international trade.
How is DC03 (1.0347) different from DC01 steel coil?
Compared to DC01 (the basic grade), DC03 (1.0347) offers superior deep drawability and ductility. Key differences include: DC03 has an elongation rate of ≥34% (vs. DC01's ≥28%) and a lower yield strength range (120-210 MPa vs. DC01's 140-280 MPa). This makes DC03 ideal for complex forming processes (e.g., shallow to medium deep drawing) in automotive and home appliance industries, while DC01 is better for simple bending or stamping.
What are the key mechanical properties of DC03 (1.0347) steel coil?
GNEE's DC03 (1.0347) features stable mechanical properties optimized for cold forming:
Yield Strength: 120-210 MPa
