What is DC05 +ZE?
DC05 +ZE is DC05 supplied in the +ZE condition — pick when a smooth, paint-ready corrosion-protected surface is needed without losing deep-drawability (2.5–10 µm Zn per side). DC05 +ZE has a yield strength of 165 MPa (23.9 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of steel grades. Elongation at break is 40% and the elastic modulus is 210 GPa (30.5 Msi). DC05 +ZE 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). CR is the default condition FabDigit quotes; +ZE is available on request or by drawing note.

Working with DC05 +ZE
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.
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 +ZE — frequently asked
What is DC05 +ZE used for?
DC05 +ZE 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 +ZE?
DC05 +ZE has a typical yield strength of 165 MPa (23.9 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 +ZE easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 53% 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 +ZE be welded?
Yes — weldability is rated very good (80/100). 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 +ZE?
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.
Can DC05 +ZE 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.
What is the maximum service temperature of DC05 +ZE?
DC05 +ZE is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
