Cold Rolled steel
 |
Steels for bending and deep drawing
applications are intended for the various
applications of cold forming. They are used when
deformation and ductility properties are more important
than strength properties. These steel grades are
suitable for a wide range of surface finishing like
phosphating, painting, electrolytic galvanizing, etc.
Typical applications are to be found in the automative
industry, the deep drawing sector, the metal processing,
the building industry and the manufacture of profiles
and tubes. These grades can be used for normal (DC01) up
to deep drawing applications (DC04).
