Pickled

Steel for cold forming and deep drawing EN10111:2008

AREAS OF IMPLEMENTATION

  • Industry

  • Building

  • Transport

  • Metal structures

  • General metal carpentary

  • Naval

Characteristics

These steels are characterized by maximum yield limits and minimum guaranteed breaking and elongation. They are classified in ascending order of formability and can therefore be used for various cold working, from less critical moulding (DD11) to the deepest drawing (DD14).

They are supplied with a pickled and oiled surface, but it is possible to have black material.
