DC05
1.0312Cold-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.
