DC01 Steel Sheets - Precision and Durability for All

DC01 is a cold-rolled low-carbon steel (European standard EN 10130) with the material number 1.0330, also known as St12 or FeP01 in some regions . As the basic grade in the DC steel family, it's specifically designed for cold forming applications requiring excellent precision and formability .

Chemical Composition:

• Carbon (C): ≤0.12% (low carbon content ensures high ductility)
• Manganese (Mn): ≤0.60%
• Trace elements: Aluminum (Al) is often added to improve deep drawing properties

Mechanical Properties:

• Yield strength: 140-280 MPa
• Tensile strength: 270-410 MPa
• Elongation: ≥28% (superior ductility for complex forming)
• Rockwell hardness: 40-75 HRB
• Excellent deep drawability (r-value ≥1.8)

DC01 steel excels in precision through three key aspects:

1. Superior Dimensional Control

Thickness tolerance: ≤±0.02mm

Width tolerance: ≤±0.1mm

Flatness: minimal bow and camber (no "sickle bend" effect)

2. Surface Finish Perfection

Surface roughness: Ra≤0.8μm (smooth enough for automotive exterior panels without additional polishing)

No oxide scale (unlike hot-rolled steel)

Consistent texture across the entire sheet

3. Forming Precision

Excellent springback control (deformation stability after forming)

Planar anisotropy <0.3 (for rotationally symmetrical parts with uniform wall thickness)

Minimal earing (edge irregularities) in deep drawing operations

DC01's durability stems from both its inherent properties and available surface treatments:

1. Intrinsic Strength and Stability

High ductility (≥28%) allows it to absorb energy without fracturing

Good fatigue resistance under repetitive loading

Structural integrity maintained even after cold forming

Processing hardening capability (via controlled deformation, strength can increase to 390-640 MPa for specialized variants like DC01-C390/C490)

2. Surface Protection Options

Automotive Industry

Body panels and doors (smooth surface for painting)

Interior components (dashboard supports, seat frames)

Structural parts (chassis brackets, door reinforcements)

Wheels and wheel components (DC01-C590 variant)

Electronics & Appliances

Server and computer cases (with precise dimensions for component fit)

Display brackets (thin, lightweight yet rigid)

Home appliance shells (refrigerators, washing machines)

Smartwatch components (straps, bezels)

Industrial & Precision Manufacturing

Shim stock (for precise spacing in machinery, with thickness down to 0.001mm)

Connectors and brackets

Medical device components (requiring consistent thickness and surface quality)

Precision tubes (for fluid systems with tight diameter tolerances)

Construction & Architecture

Facade cladding (with aesthetic appeal and weather resistance)

Lightweight structural elements

Roofing components (with corrosion resistance in harsh environments)

The Perfect Balance: DC01 offers an unbeatable combination of formability, precision, and durability at an economical price point. Its low carbon content makes it easy to work with (welding, brazing, stamping) while maintaining structural integrity .

Versatility Personified: From simple bending to complex deep drawing, DC01 adapts to diverse manufacturing processes without compromising precision or durability .

Customizable for Special Needs:

DC01-A: Accepts minor defects that don't affect formability

DC01-B: Premium surface quality for demanding decorative applications

DC01-C series: High-strength variants (390-690 MPa) for structural applications

DC01 steel sheets are the go-to material when you need reliable precision and lasting durability without breaking the bank. Whether in automotive bodies, home appliances, or precision machinery, this versatile low-carbon steel delivers consistent performance, making it a staple in modern manufacturing.

What is the difference between DC01 and DC04 steel?

DC04 and DC01 are both cold-rolled, unalloyed quality steels that are used for various industrial applications. While DC01 serves as the standard grade for general cold forming processes, DC04 is characterized by improved deep-drawing properties and higher ductility.

Is DC01 the same as CR4?

Cold Reduced steel

Here at GNEE Steel, we stock and process DC01 mild steel (often referred to as CR4), in varying thicknesses from 0.9mm up to 3mm. Each sheet is de-coiled and flattened to strict tolerances in our works, ensuring consistent quality and flatness, every time.

What does DC01 mean?

DC01 represents the basic grade of the DC steel family and is also known under the former designations St12 or FeP01. This grade can be used for simple forming operations such as bending, coining, beading and drawing.

What is the difference between DC01 and DC03?

DC01 – This grade can be used for simple forming work, e.g. bending, embossing, beading and drawing. DC03 – This grade is suitable for forming requirements such as deep drawing and difficult profiling.

What is DC01 steel equivalent to?

Material 1.0330, DC01 steel equivalent to ASTM, ISO, European (German DIN, British BSI, France NF), Japanese JIS and Chinese GB standard (for reference). Note: DIN 1623 has been replaced by DIN EN 10130, and the designation ST12 has been replaced by DC01.

What is the thickness of DC01 material?

Galvanized Steel Sheet - Grade Dc01, Thickness 0.2-3.50mm, Width 914-1250mm | Cold Rolled, Durable Zinc Coating, Long Lasting Toughness.

Is cold-rolled steel better than hot rolled steel?

Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling. It is also up to 20% stronger than hot rolled through the use of strength hardening.
