DC05 vs DC04: Adjacent drawing grades — DC05 has best formability in the series
DC05 vs DC04
Side-by-side chemical composition and mechanical property comparison.
Overview
DC05
1.0312
Cold-rolled steel for extra deep drawing. The highest formability grade in the EN 10130 drawing steel series (r-value ≥1.8). Very low yield strength for excellent deep drawability. Used for complex deep-drawn automotive body panels (doors, fenders), kitchen sinks, washing machine drums, and any severe stamping application.
DC04
1.0338
Cold-rolled low-carbon steel for deep drawing. Higher formability than DC01/DC03 — suitable for difficult drawing and profiling operations. Used for automotive body panels, deep-drawn kitchen sinks, complex stampings, and precision-formed components.

Compatibility Assessment
DC05 has lower C (0.06 vs 0.08%), lower YS (100-160 vs 120-180 MPa), and higher r-value (≥1.8 vs ≥1.6) for superior deep drawing. DC04 is sufficient for most draws and slightly stronger. Choose DC05 for the most demanding stampings (deep fenders, complex shapes).
