SPCC vs DC01 Cold Rolled Steel Grades Comparison

Product Details

SPCC (commercial grade) and DC01 (European standard grade) are the two most popular cold rolled steel grades with the highest search traffic. They are widely used in B2B procurement, but there are key differences in performance and applications. Below is a detailed comparison to help you choose the right one:

Comparison Item	SPCC (Commercial Grade)	DC01 (European Standard)
Mechanical Performance	Yield ≥130MPa; Tensile 320-410MPa; Elongation ≥35%	Yield 130-270MPa; Tensile 320-420MPa; Elongation ≥34%
Formability	Good, suitable for general bending and stamping	Better, more ductile for complex forming
Weldability	Good, suitable for general welding processes	Excellent, stable performance after welding
Surface Finish	Smooth, no scale, standard commercial finish	Higher precision, smoother surface for high-aesthetic needs
Typical Applications	Hardware, general structural parts, simple stamping parts	Home appliances, automotive parts, precision stamping
Cost	More cost-effective, suitable for bulk general use	Slightly higher, ideal for high-precision projects

Both grades have the same basic chemical composition (wt%): C ≤ 0.12%, Si ≤ 0.05%, Mn ≤ 0.50%, P ≤ 0.035%, S ≤ 0.035%, Fe balance, ensuring good weldability and formability.

Pro Tip: Choose SPCC for cost-sensitive, general-purpose projects; DC01 for high-precision, high-aesthetic applications like home appliances and automotive parts.

Common grades: SPCC, SPCD, SPCE, DC01-DC06, Q195-Q235. Core mechanical properties (typical):

Steel Grade	Yield Strength (MPa)	Tensile Strength (MPa)	Elongation (%)
SPCC (Commercial)	≥130	320-410	≥35
SPCD (Drawing)	≥120	300-390	≥38
DC01 (European)	130-270	320-420	≥34

Chemical composition (wt%): C ≤ 0.12%, Si ≤ 0.05%, Mn ≤ 0.50%, P ≤ 0.035%, S ≤ 0.035%, Fe balance, ensuring good weldability.

Cold Rolled vs Hot Rolled Steel: Key Differences

Item	Cold Rolled Steel	Hot Rolled Steel
Surface	Smooth, no scale	Rough, with scale
Precision	High	Low
Thickness	0.2mm-4mm (thin)	3mm+ (thick)
Cost	Higher	Lower
Applications	Automotive, appliances, precision parts	Construction, heavy machinery

Typical Applications

Automotive: Body panels, door frames, battery casings (new energy vehicles).
Home Appliances: Refrigerator/washing machine shells, TV cabinets.
Construction: Interior decoration panels, door/window frames, 5G base stations.
Industrial: Precision machinery parts, tooling, pressure vessels (with corrosion protection).
Electronics: Smartphone/laptop casings, precision stamping parts.
