China 2021 China New Design 1008 Cold Rolled Steel - EN 10130 DC01 Steel 1.0330 cold rolled steel flat sheet - Ruiyi Manufacturer and Supplier | Ruiyi

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 Meaning and Definition

• D: (Drawing) flat products for cold forming
• C: Cold rolled
• DC01: Drawing quality
• DC03: Deep drawing quality;
• DC04, DC05: Special deepdrawing quality;
• DC06: Extra deepdrawing quality;
• DC07: Super deep drawing quality.

• 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

• 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
  	EN 10152	DC01+ZE (1.0330+ZE)					A, B
  	EN 10139	DC01-C390, C340, C440, C490, C590, C690					–

  Notes:

  • EN 10130 – Cold rolled low carbon steel flat products;
  • EN 10152 – Electrolytically zinc coated cold rolled steel flat products.

  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.
