DC04: deep-drawing and forming properties
Elongation and r/n values using SSAB Form 04 as an example meeting DC04 requirements.
Sources checked:Understand the Material
SSAB Form 04 is deep-drawing sheet that meets or exceeds EN 10130 DC04 requirements. The table applies to this manufacturer product. Values measured transversely require care when compared with results from other specimen orientations.
Minimum A80 elongation decreases by 2 percentage points for 0.5 mm < t ≤ 0.7 mm and by 4 percentage points for t ≤ 0.5 mm. r90 and n90 apply only when t ≥ 0.5 mm; the minimum r90 decreases by 0.2 when t > 2 mm. Press geometry and lubrication also affect the result.

Applications & Selection Notes
Deep drawing and complex pressed components. These values do not imply that every cold-rolled sheet behaves identically.
