What is DC05?
DC05 (1.0312/1.0389, SPCE) is a deep-drawing low-carbon cold-rolled sheet steel in the EN 10130 family, softer and more formable than DC04 with a formability score of 97. It is supplied as cold-rolled coil and sheet, including electro-galvanized (+ZE) versions, at 160 MPa yield, 300 MPa tensile, 42% elongation and 85 HB, and is rated to about 300 °C. Corrosion resistance is nil (score 10), so it must be oiled for storage and then coated. DC04 is the cheaper choice when the draw is less severe. DC05 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,480°C (2,696 °F). DC05 has a yield strength of 160 MPa (23.2 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of steel grades. Elongation at break is 42% and the elastic modulus is 210 GPa (30.5 Msi).

Working with DC05
Is DC05 easy to machine?
Soft and gummy — use sharp positive-rake tools, high speed and generous coolant to avoid burrs and built-up edge; mostly blanked/pierced rather than machined.
Can DC05 be welded?
Excellent for resistance spot, MAG and laser welding with no preheat; on +ZE grades increase current/electrode maintenance and ventilate zinc fume.
Can DC05 be formed, bent or molded?
Designed for severe deep drawing and stretch forming (r90 ≈ 2.0, n90 ≈ 0.21); form within a few months of delivery and use non-ageing (ULC/IF-type) stock to avoid Lüders stretcher strains.
DC05 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on DC05?
Must be protected: oiling for storage, then zinc phosphate + e-coat, powder paint, or electro/hot-dip zinc; takes plating and painting readily with a smooth skin-passed surface.

DC05 — frequently asked
What is DC05 used for?
DC05 is typically used for deep-drawn housings, fuel tanks, cans and automotive panels. In short: top deep-drawing CR grade; more formable than DC04; low yield, high elongation.
What is the yield strength of DC05?
DC05 has a typical yield strength of 160 MPa (23.2 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of steel grades. Strength varies by condition: see the 2 listed tempers.
Is DC05 easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Soft and gummy — use sharp positive-rake tools, high speed and generous coolant to avoid burrs and built-up edge; mostly blanked/pierced rather than machined.
Can DC05 be welded?
Yes — weldability is rated excellent (95/100). Excellent for resistance spot, MAG and laser welding with no preheat; on +ZE grades increase current/electrode maintenance and ventilate zinc fume.
What surface finishes work on DC05?
Must be protected: oiling for storage, then zinc phosphate + e-coat, powder paint, or electro/hot-dip zinc; takes plating and painting readily with a smooth skin-passed surface.

What is the maximum service temperature of DC05?
DC05 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does DC05 cost?
DC05 is a budget-cost steel ($), cheaper than about 90% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
